its coming along, the dash isn't bad, Im waiting on getting the windshield to put the dash in and finish it up, I have to use the parts to help hold the vinyl in place because I can't find a glue strong enough to hold it in place, so once I get it installed I'll put in the guages to finish off the last part of the dash.

ok got a question. for the side drip rails/window gasket track, circled in yellow
75 el camino project.  - Page 6 El_cam10
is there a seal between the chrome trim to body? I know there is one between the window gasket track and chrome but I cleaned the chrome too good I can't tell if there was anything. and also does anyone know if there is any kind of sealant on the A-pillar pinch weld cover.

Here is the stuff you need under your drip rails. Its not like what the factory used but it will work. Not sure what you mean "plastic that protects the glass from the touching edge of the trim around the front and rear window". Do you have a pic?

That plastic you mention is part of the window trim itself. Its not really needed but it did come from the factory. I dont think it was an anti-squeak but more of not allowing dirt to get under the trim that easily. Very thin, black plastic thats on the bottom side of factory trim.

All my original trim has it. I'd grab a pic but my trim is currently all tucked away. I wouldnt be concerned using the trim without it especially if the car is garage kept. Most cars I see dont have it or its broken off.

most of my trim has it but its really brittle and broken off in spots, and the top one has like 4 2inch sections of it spaced out, making me think it was protecting the glass from the aluminum from making noise or scratching it, Ill get pictures of it today but that is exactly what I was talking about.

I ended up using truck cap seal and trimmed it where needed, seems to work pretty well.

been working on re doing the engine bay wiring, old, mostly all brittle, faded, and honestly didn't feeling like worrying about someone else's gremlins so ran most new wire with new terminal crimps. Got all the light circuits done and where they need to be, and got most of the engine wires done, just a few I can't figure out; electric choke color wire, where the starter wires go, one is a power wire that junctions with the alternator power wire and has a fusible link on it, the other is either black, brown, or maybe even purple (i'm color blind, combined with 50 plus years of dirt and grime) and has like a plastic nub on it by the eyelet. that wire is original, wasn't sure if the nub was important

75 el camino project.  - Page 6 Imgp5610
75 el camino project.  - Page 6 Imgp5710

and where the wire shield goes. someone said one side mount to the starter its self, Im guessing the lug with 2 nuts on it on the back of the motor casing itself, just not sure where the other end goes,

The two small studs with nuts on the rear of your starter. If you look carefully right next to them, one of them should have an "S" on the plastic. Your purple wire, with the small ring end, should go there. Purple wire gets hot when you turn the ignition key to start. Its what tells the starter to crank the engine.

That'll be the main feed back to the horn relay -- it's the primary feed for every circuit in the car.  From there it will branch out to everything else. Hence the connection from the alternator, as the alternator actually powers all that when the car is running.

As Joe mentioned, that wire is actually purple and is the starter feed from the key to start the car.

thank you for the confirmations, I hooked the little wire to the s terminal, and the bigger one to the big lug. and with a little looking on here I found someone with a picture with the header off showing how the tube gets bolted to the tarter and the trans mount bolt.

next onto figure the rest of the wiring, mostly the choke wire and rebuilding the carb.

got some more done, carb is rebuilt, didn't look too bad, but the secondarys were seized closed so got those to work again, whats the point of a 4 barrel if you can't use it. got the instrument cluster in
75 el camino project.  - Page 6 Imgp5715

got the bracket under the dash figured out
75 el camino project.  - Page 6 Imgp5716

still a few wires I gotta get figured out where they go, like what connects to the right rear marker that goes up from the passenger side. none of the connectors match up. and a few more that I have no idea

this one, brown wire kinda reaches under the air box with a clip to keep it up somewhere
75 el camino project.  - Page 6 Imgp5717
this one is a weird female spade type with a black wire that has another black wire that seemed to connect to make it longer but still no idea
75 el camino project.  - Page 6 Imgp5720

and this one is like a pink and brown connected on one terminal and seems like it might go to the neutral safety switch
75 el camino project.  - Page 6 Imgp5721

also got the passenger door panel on but the back edge seems like there is a huge gap between it and the door. but the top looks like it lines up perfectly.

Check to see if it has 12V when you turn on the ign switch. If so, my guess is it's the main power feed for the selector switch. It appears to be the only free-roaming brown wire in the HVAC neighborhood. The other side of the connector will have 2 yellow wires, which transfer the juice to the selector and the thermoswitch on the engine block.

The backup lamp switch will be pink and lt green.  Neutral will be two fat purples. This would appear to be that same feed for the HVAC (brown wire) from the fuse box, and the pink splices in to feed the GEN light.  This makes me think I'm looking at the wrong end of the brown wire in the previous post -- look at that wire and see where the other end is.  One end should be to this connector, and the other end should be the two yellow wires I mentioned.  It's possible I was thinking the loose end of the single brown wire above was the connector for the two yellow wires, when it actually might be the thing that connects to this one.

Can you take a shot at a better angle, like from the side? Can't really make out anything here...

ok got better pictures and more info, and thank you for the help, when I got this before I tore it down the wiring was already removed on this body and the other one was hacked and slashed so I have very little to go on, most of it I was relying on the wires memory and following how it wanted to be to figure out what it went to. and I know gm liked making one harness fits all so there may be extra connectors and plugs that don't get used and the radio wires are a whole nother problem that I will have to contend with when I get one.

the brown wire by the air box is a male spade that is spliced with another brown wire at the thermal switch, with a yellow wire, both of the other ones go over the air box and I can't follow them.    
75 el camino project.  - Page 6 Imgp5725
75 el camino project.  - Page 6 Imgp5726

the neutral switch I have a 2 purple which I think is reverse light, and a green and pink which I think is from the ignition, and 2 more blades that I don't know about, should there be anything on them?
75 el camino project.  - Page 6 Imgp5727

this is a side of the single black wire it goes into the large harness that goes to the back of the instrument cluster. and the black box might be the turn signal flasher maybe? goes into the same harness as that, and the second picture is with the wire that was attached to it reconnected, it has a single female terminal. and its long enough to reach anywhere in the cab so I'm at a loss. right now I'm not quite ready to put a battery on to test anything, worried about loose wires sparking, but soon I'll have to just to see what is missing.

Okay, I misspoke above (and I went back and corrected it), the pink/lt green are the backup lights, and the two fat purple wires (1 should have white stripes) are the neutral safety switch to the starter.  This is what happens when I look at this stuff without enough caffeine.

The remaining blades should for the seat belt sensors (yellow w/black stripe and a black wire).

Okay, this one has me scratching my head.  That's not the thermo switch -- the thermo switch is screwed into the engine block.  The problem is I can't find that thing in any of the diagrams, either 73 or 76 (thinking maybe it came after my 73), and I can't find any combo of two browns and a yellow in the same connector.  Still looking, but I'm limited to the diagrams and manuals since all of that is gone in my car.  Maybe someone else can chime in with what that thing is, but I'll keep looking in the meantime. scratch
