OK, I realized I hijacked an unrelated thread so moving my concerns here. Thanks again to Chris1956 for last reply.

I'm in the process of rewiring 17' Montauk that was previously a horror story.

Wiring diagram in my Seloc manual indicates the #5 pin (gray) of the harness connects to the rectifier from the stator. According to ABYC that is the color for the tach input.

Do I use that wire at the other end of the harness for the tach sender terminal ? The other five reaming are for ignition and start bypass.

Wiring diagram is typical for the L6 90,115 and 140 - 1980 to 1989 (In Seloc)

It would seem 12 amps is not very much compared to the V6's using a 40amp stator. Also, I find it interesting that on all other V's the amp ratings are shown in diagrams but not on the L6, At least not in the Seloc manual I'm using.

A separate 3-cond. cable ran with the engine harness through the gunel just for the trim solenoids, if possible, I'd like to eliminate that cable and combine everything into one multi-cond harness cable to clean things up. Previous owners had a convoluted corroded rats nest of wiring.

On this engine end of the harness female socket for pin#2 of the harness (purple) is void (no wire). Pin#5 (gray) was snipped and not connected to anything at the ignition switch end. I assume the reason for the separate 3-cond. cable was for supplying greater current capacity than what the #8 +red pin of the harness was meant for. Looking at other wiring diagrams of early V6 with similar 8-pin harness it appears that the #2 pin would provide + pwr. for the trim solenoid via a separate terminal block and 40amp regulator.

Any further help or comment much appreciated. :)

The grey wire to the tach goes:
1. To either stator wire on a rectifier, or
2. To the gray tach wire on a regulator.

It all depends on what you have on your engine. Tach's the same.

hope it helps

Groovy.. I was pretty sure but wanted an expert opin. The grey wire does attatch to the rectifier term and is also to the stator from the same terminal post.

I now wish I could get that manual I see via a link on here, but all I get is an index page an no way to download pdf's from there. A little confused on how to actually get em. There was one used OEM on Ebay for 32.99 but it's long since been sold. From what I read, the Clymar manual is'nt much better than the Seloc either.

Thanks John.
