Trying to find "hot-all-the-time" wire on '76 ign.

[Lilleyvanilli]

Trying to troubleshoot an ignition problem and have the wiring diagr., but still a bit 'iffy' (trying to bypass ign. switch/start car to test). I have seven leads on switch, but only 6 are being used:

1. Green (double wire)

2. Green (double wire)

3. Violet (Single)

4. Black/white (single)

5. Red (single)

6. Red (single)

7. Grey (on schematic, but I don't see a grey wire on my car)

The greens and violets, as far as I can tell, go to various high beam, low beam, turn signal, heater blower, horn, etc.

The black/white goes straight to starter.

This leaves the 2 reds: both go to something called "Solider Tag 30" (#19 on key) and has (according to schematic) 7 red wires coming in/out. Where is this thing on the car?

ONE of the reds traces from this "Solider Tag 30" back to #2 fuse (controls hazard flashers, interior light, clock). Sounds like this is the one, eh?

THE OTHER red looks like it goes to + battery or alternator.

BUT... where is my coil wire? I do see one green(#44) that does not directly go to the ign. switch, but does look like it meets with one at a plug connector (if this is it, I've got 4 greens to choose from).

AND THE BIG QUESTION: If I want to bypass my ign. switch to start car for a test, which color wires do I bridge (and if one is red, which of the two reds?)

thats funny im going through the exact same thing right now, im trying find the correct pin on the back side of the ignition cylinder to connect my msd 6a cdi box. let me know what you come up with?

Red= Battery +

Violet= key on accessory and run

Green= key on run

Black or black/white= Starter excite

To remote start or bypass the the ign. switch to start from INSIDE the car jump the black/white to either of the Reds... BUT I usually bypass the ign. by going to the black/white wire at pin #7 of the little orange capped diagnostic connector by the fuse box in the engine bay, and jump that to #1 red battery+.

BE SURE THE TRANS IS IN NEUTRAL FIRST!!!!!!!!!

Simple enough....

I read somewhere on the forum that you could go to that little orange diagnostic plug and take a piece of wire from slot #1 to #7 and the car would start.

The 3,4 and 5 slots have no wires. Is it possible you mean #7, not #9? (not sure which is right side up, as 1,2,3 could be 3,2,1, or 7,8,9 might be 9,8,7.)

Ah, also thought, I could just take a multimeter/testlight and ground, then touch each red wire with the key off and see which one shows a reading, right? That would be hot all the time, eh?

Ah, memory fails me, it IS #7 (black/white) that is starter excite, And YES #1 is red........ edited original post.

Not sure about the hole numbering system on the diagnostic plug, but the hole that works with my remote starter is the outside (of the car), rear one. According to Tom's picture below that is hole #7.

HA!

I finally get to use the little orange plug!! I LOVE our cars! multiple starting systems...intermittant wipers... a key that can be removed and lets you car run... headlights that automatically turn off when you remove the key so you don't get a dead battery... impossible to lock the keys inside... Where is all our new technology taking us? To the mechanic, with a quick stop by the bank?

Yes, the numbering is a bit vague on the plug itself, but just bridge the black/white wire with the red and she starts right up!

I also did this at the switch with the two wires and she starts right up.

I also used a large flat blade screw driver to turn the switch (instead of the key) and she starts right up.

I also put it all back together and used the key and she starts right up. This "I'll start when I want to" issue is truly my nemesis. Going out to see how she 'feels today'....

Here is the best diagram of the orange diagnostic plug I have found...
