I'm suffering from my own lack of notes here and I'm hoping somebody can help me out.

I'm building a custom wire harness and gutted the old one (including fuse panel, starter circuit, and TSSM) several months ago. I though I had ID'd everything at that time but now I'm seeing a wire I missed (or never could ID?)

It's a Black wire with two Green stripes (one on each side) at pin 11 of the black ignition module plug.

This is from a 99 DWG, carbureted, with a cam position sensor.

I've looked thru all the wiring diagrams I can find and can't seem to find it. That leads me to believe I don't need it, but I'd rather confirm its function before I get too deep into the new wire routing.

Many thanks in advance!

No Joy on Green and Black after checking all my Wiring Diagrams in the 05 Service Manual for all Dynas ..

 

I appreciate the effort regardless. Thanks!

A bunch of Googling turned up one tech post mentioning that pin 11 should be grounded if not using a TSM or BAS. I am using the BAS, and it definitely doesn't connect to that. My TSM is looong gone and I don't recall ever having to modify any ignition wiring to make the Badlands Illuminator work...

Still...pretty much every other small black wire regardless of striping is a ground of some type, so that checks out. If I don't hear otherwise from the sage folks here, I'll run to the ground stud and keep it isolated until I confirm the engine starts (or not).

 

Hmm... I went back and looked again. Both the 99 and 00 main harness diagrams show a black wire to ground on pin 11. Mine is clearly black and green.

I'm going to trust the pinout over the insulation color and go ahead and ground it.

Hopefully it works. I think it will.

 

Chris,
According to the wiring diagrams I checked MoCo started to use BK/GN wires as a ground wire on 08 models and later.

Interesting. Maybe the PO had something repaired?

 

Hard to tell. What bothers me is the fact that the diagram shows the ground wire connected to pin #12 whereas it is connected to #11 at your connector ...

 

The ignitions have changed several times since 99. Even '01 is different than 99...no cam sensor...

Pin 12 is the tach signal output on mine. I know that for a fact. Used it.
