8 Pin Connector In 64 Monza?

[HotManInMS]

I've been trying to work through the electrical issues, and one issue I have is resolving the diagrams vs what I'm seeing. The 64 engine wiring has a 12 multi point connector while my engine has an 8. Did they use 8 pin connectors in some of the engines?

Actually, the shop manual diagram in the 1964 supplement (attached) has a rectangular 10 pin multi-connector in the passenger car schematic diagram. The 1964 Corvair 95 (Truck and Van FC) used a square-shaped 8-pin multi-connector in the engine compartment.

Can you post close-up pictures of the Body Tag (engine compartment), VIN Tag (Driver's Door Jamb), and your engine compartment multi-connector?

I dont currently have one of the connector. Here is the build plate.

My 64 came with an 8 pin connector . It was changed recently as I got new harnesses from Clarks ; both the rear harness and the main , which both came with 8 pin connectors.
I may have some connectors and terminals for this connection . If you just want to change them you will need a CORRECT crimper . Do not use a general purpose one .
If you want you can pull the wires out of both connectors and tie the together outside the connectors using a butt connector .

[HotManInMS]

I'm fine with the 8, but does that mean I need to use the wiring diagram from 1963?

[corvair500]

The 8 pin is all that Clarks sells for this connection .

[corvair500]

I suggest that if it is within your budget , get , at least, the engine harness and replace that . Be very careful to connect the correct wires at the generator . Otherwise this harness is very easy to replace . I also changed the main harness but found two wires to have been crossed in that .... the only part I ever got from Clark that was defective . His manufacturer seems to have an issue with quality control .

[HotManInMS]

Wouldn't the harness have a 10 pin connector?

[corvair500]

No , the only harness Clarks sells for the 1964 are 8 pin .

[HotManInMS]

This is so confusing.

Did it come 8 pin from the factory, or did someone swap it over at some point?

[corvair500]

Sorry that it is confusing ... My 1964 came from factory with 8 pin .... someone apparently changed your connector . Eight pin must be standard , I think some of the wiring diagrams must have mistakes . If you order one you will get 8 pin . Now if the engine harness is 12 pin , that must be corrected so they will plug in to each other .....

[corvair500]

meant to say that if your MAIN harness is 12 pin , that will have to be changed to connect to the correct 8 pin harness

The Clark's Corvair Parts online catalog includes photographs of the MAIN BODY HARNESS, from the dash to the engine compartment connector.

Engine Compartment Wiring Harness Connector (8-pin)

The shop manual supplement passenger car schematic diagrams show this 8-pin engine compartment wiring harness connector in their 1962-1963 diagrams, but then show a 10-pin connector in their 1964 schematic diagram. I don't see the 1964 10-pin connector in the photographs below, and Clark's makes no reference to it. Perhaps this was an engineering documentation error at GM.

Perhaps a clue to this mystery comes from further examination of the published 1964 schematic diagrams. In the 10-pin connector depicted in the 1964 shop manual supplement diagram, the 10th pin is unused and the 9th pin is only used to tie to the engine temperature warning switch for the "600 ONLY", and makes a tie to the temperature warning light circuit. The "600 SERIES" (coupe and convertible) was the Spyder, and that 600 Series designation only existed in the 1964 model year. (In 1962 and 1963 the Spyder was a variation of the 900 Series Monza). There seemed to be a confusion factor at GM in the 1964 model year, and then the LM 1965 Corvair revision and redesign was revealed.

So it appears likely that an 8-pin multi-connector in 1964 was normal. Since I don't own a 1964 Corvair, I cannot go out to the garage and look.

No, mine came with an 8 pin.

Okay, so here's the question, if the wiring diagrams for the 1964 on the internet show a 10 pin connector, should I reference the 1963 diagrams, which show an 8 pin connector, when I wire my engine compartment?

If there a 1964 engine wiring diagram that shows a. 8 pin connector?

I revised my comments in the post that shows pictures of the wiring harnesses, as shown above.

I carefully compared the 1964 (10-pin connector) and 1963 (8-pin connector) wiring schematic diagrams. From top to bottom, the left and right connectors are functionally identical for the first eight pins. The last two pins on the bottom of the 10-pin 1964 connector in the diagram can be ignored, and may not even exist. The exception might be the 1964 Series 600 Spyder, which might actually have a 10-pin connector in the engine compartment. Perhaps someone who actually owns a 1964 Spyder can go out and look in their engine compartment to see what they find. I suspect that most other 1964 Corvair owners will have to settle for the 8-pin multi-connector in the engine compartment.

The wire color codes appear to be somewhat different when comparing the 1964 and 1963 wiring diagrams. I would guess that the colors shown for the top eight pins of the 1964 harness diagram are correct. You will have to examine your wiring harness to confirm this.
