67 convert. Pic taken from engine side of firewall. Anybody got a clue what the round connector with two wires in the middle of the pic is for? I haven't gotten all the ay under there yet to see where the wires go. Looks like two green wires together on the dash side.
If you have a manual transmission car, then yes. From the firewall it goes to this externally mounted switch on the transmission. There is a bracket on the side case that holds this switch. Just switched my car to a 4 speed, just had to install the very plug you are asking about.
There are switches and brackets (for Muncie) available from NPD, Classic, Ames, EBay,etc. I have been looking for over a year to find a Saginaw bracket.
Yes, orig Muncie Ap. Where do the wires go on the dash side of the connector? I got my hand in up in there yesterday but lost it after it wrapped around the St column brace. I'm going to open both doors so I can really get in there and see. So this switch must just turn on the back up lights. Seeing the way it enters the pass compartment makes me think it doesn't connect thru the fuse block and just wires in some kind of loop between a power source, the switch and the lights in the trunk. Seems odd. Like it was some kind of after thought or something.
67 wiring diagram shows a pink power wire from the fusebox to the dash gauges/lights and from that terminal to the switch. Then a green wire from the switch to the rear body connector and from there to the backup lights and ground. Doesn't show that connecter though. My car, 1968, doesn't have that connector but has the hole where the connector would be. I now have a grommet in there with wires going into the under dash area. I forgot what wires I put though but could be the neutral safety and backup switch. Had neither switch when I bought the car but the TKO has both in the tranny so I wired them into the system.
Ok so I got up under there today and the two green wires that come from that connector do connect to a green wire and a pink wire behind the dash so the power must come from the pink wire and loop out to the switch and back via the green wires. I gotta get a wiring diagram for a 67. This things gonna be a nightmare to sort out. The previous owner hacked the crap out of the dash harness.
Wiring, I think that is the most common complaint of anyone who has ever bought a used car. Most of these used cars have had multiple owners and it seems everyone has added or removed something to the wiring. Radios, 8 tracks, cassettes, tachs, under dash "sex" lights, heaters, blowers, etc. Then there are all the wiring repairs done by guys who, by law, shouldn't be allowed to own a set of wire cutters. I removed an 8 track from my GTO that had six different wires spliced together for the power source. Each wire a different colour and gauge, some just twisted together and covered with black tape. After I got the electrical fire out, I removed about 20 yards of extra wire from the car.
Back when I was at the stage you seem to be at now, with the under hood and firewall wiring, I got so fed up I tore every wire out and built my own harness. The next owner will most likely complain about the guy who 'screwed up' the birds electrical system. At least I crimped, soldered and shrink-wrapped every connection, drew a schematic diagram and wrote down where every wire goes and what it's for.
And yes, pink power to switch green wire from switch to lights. Speaking of which, have you ever tried backing there birds up at night wondering why your backup lights don't light up anything? I think the brake lights do more good.
Anybody got a pic of the OE reverse light switch? I'll probably just end up fabbing a bracket for a micro switch if I do anything about it at all. Pretty low priority. Would be nice to see how they had it set up though.
