If you're using AlkyControl and Boost Harness...

Good info. Did you by chance consult Ken before posting his boost harness circuit to the world?

No, I've been trying to get ahold of Ken for a few days now with no luck. The pieces are all there for anyone to see, it's not like they were potted or anything. Besides, I don't think anybody could build one for what they go for new ($49.00). The reason I diagrammed it was because mine broke and I needed to make repairs (the wires flexed enough to snap a solder joint).

That said, I did add the ground wire from TPS terminal "C" to the MAP terminal "A" and it works fine now. This will allow the harness to function either way - boost or MAT - and still trigger the Alky regardless of function.

Russ.. great info..

The MAP not only needs power but a ground as well..

I guess that voltmeter just paid for itself.
