I have a 85 iroc. Tpi engine out of a 86 iroc. The maf burn off relay connector on the 85 harness is made like one on a 87 harness I have. Except the 87 one only has 3 wire. 2 are pink and black. 1 is tan and white.

 

to clarify the connector is next to the ECM connectors. I will post pic's shortly

 

This connector? C221 and c207

It must be the 221. I have a spare 86 dash out of a 86 z28. No connector for a 221. Must have been a carb car it come out of.

 

 

Looks like c221 here’s a picture of your harness layer out figure d

I looked at the under dash wiring and found there are 2 connectors that look alike. The one goes to maf burn off and the other up under the dash

 

Are you asking about this connector ?

 

I thought it was that it was supposed to go to. I looked up under the dash and Sean how the 85 harness has both. So the 87 engine harness with my 86 engine and ECM/ maf sensor stuff should do the job. Thank you for your time and effort.
