Too many projects...too little brains

Hello, glad to be a member here. I have a 77 elcamino, 86 Monte Carlo, and a 83 silverado I plan to swap to efi in the near future. The meano and monte I plan to do tpi and the silverado I'm concidering the same. I have a cpfi 4.3 swap under my belt as well as a tbi swap back in high school. I would like some info on breaking down the tpi harnesses. Mainly what can be deleted in the pin outs for stand alone use. Info on both SD and maf plz. I have one of each. Thanks! Justin Grindle
