Please bear with me i am new to forums and posting. Anyway I have an 85 Z28 and would like to swap to and upgraded ECM i did find the instructions on our web site and most of it looks pretty straight forward except some of the splicing I get the injector wire slice but the maf splicing is loosing me a bit as i read it the left hand column are the old wires you splice together and the right hand column is where the spliced wires connect to, where i get confused is what appears to be step three maf burn off pin c, maf burn off pin e and maf power pin e. The original connector for the burnoff module only has one pin e am i missing something here or is it just me. any help would be appreciated.

 

See if the info at this link helps:

thanks for the reply RBob. I have been to the link that you suggested that is what got me intrested in the swap it seems quite easy but the splicing process seem a bit confusing and unclear to me. If they are clear to you maybe you could explain them to me, it seems to me that the relays and pin locations listed on the left refer to the 86-89 relays that are being installed?
