Well, I guess today will work. I can probably figure out the wiring for that. Thank you.

I have another question along the line of this kind of conversion. Could I use the tach signal off an HEI for the CMP, or does the PCM need to see a CMP signal? Otherwise, what would be a good method of getting a CMP signal?

BTW Antis, I'm not to worried about the engine model like the L31, Just a map I can start with. plan for two conversions. Both older 350 blocks. One getting a TPI with the Vortec edition lower intake manifold. Other getting a mod'd LT1 Intake with either mod'd LT1 heads or Ported 416 heads. Or shoul...

And I can't get that 2 pin alternator to charge so I dropped in an earlier 4 p...

I have a 2013 Sierra that already needs one replaced. to me its a brand new truck and already ...

I think you need to give more info on your current setup. Engine, pcm, OS, tac module. And what have been done. 4.3l, p59, currently 7811 but unable to locate xdf so trying to switch over to 6703, tac module?, very little done, just been trying to disable vats or figure out why else the truck wont ...
