Help - C2 Bulkhead Connector Pinout?

[Glenn B.]

Decided to investigate my periodic issue with my starter not engaging.

I removed the wiring harness connectors from the bulkhead - and one of the pins from the fusebox side came with the harness connector! - I am hoping this is the starter solenoid wire - would explain my issues.

It is the passenger side connector and it is the pin on the bottom, closest to passenger side. I don't want to remove the tape from the harness to determine the wire ID (color).

Can somebody tell me what wire colur / ID this pin is? Trying to figure it out from the wiring diags in my assembly manual - but it is not clear.

Is it possible to replace the pins in the fure block - or do I need to buy a whole new block?

If I've interpreted the assmebly manual wire diag correctly - it is the B/W wire for the M35 (Auto trans) safety switch - which would be a stroke of good luck - because I'm an M21

I believe you are correct that the terminal in question is a black/white wire. However, I think it goes to the ammeter.

From further investigation it appears to me that the purple wire to the solenoid does not go through the bulkhead connector for 1967. It does for 1968 and later.

As far as the terminals within the bulk head connectors are concerned, I believe they are replaceable separately without the need to replace the entire connector. I've never had to do one, though.

You are (as usual) correct on the B/W wire. I traced the other side of the diagram and it goes to the -ve side of the ammeter. There is a notation on the diagrams I have (for 66) that talks about a switch for M35 - the placement of the text on the diag next to the wire in question confused me.

Guess I can live W/O the ammeter for a while.....

Are you sure the solenoid switch does not go through the bulkhead? - it does on the 66 diagrams I have. There is an in-line connector for the ppl (solenoid) wire near the windshied motor (I believe this is what optionally goes to a safety switch with M35) - the source ppl wire comes from the harness - I assumed it originated at the bulkhead connector per 66?

For 1966, the purple wire from the starter solenoid "S" terminal to the ignition switch does go through the bulkhead connector. The reason for the M-35 reference is that, for M-35 applications, the neutral start safety switch is wired into this circuit. It serves as a switch to interrupt the current flow to the solenoid from the ignition switch if the transmission gear selector is not in the correct position. That's how it effects its safety function.

For 1967 it appears to me that the purple wire circuit is different. It still has the optional M-35 neutral start safety switch in it but it does not seem to pass through the bulkhead connector. It appears that it may have an in-line fuse. As a matter of fact, this was quite surprising to me. I was completely unaware of this difference for the 1967 model year.

By the way, if I'm right about the 1967 purple wire circuit configuration, I wish they had left it that way for ever-after. Having the wire by-pass the bulkhead connector eliminates one possible problem area.

That's correct - from '63-'66, the purple ("start") wire went through the inboard bulkhead connector, but in '67 it became a separate wire that bypassed the bulkhead connector, but it retained the in-line connector just above the wiper motor.
