My son and i Are working on a 88 IROC 350TPI, trying to identify three plugs. The first two or near the A/C wiring up front on passenger side, one it light blue/green and one is light blue/ white. Last plug is driver side in front of washer reservoir it is light blue and pink.added pics for reference. Thanks in advance for any help.

 

I'm taking a 3:30 AM complete stab in the dark guess based on location, and old man rip all that emissions crap out of there idiot mentality that was rampant during the time these cars were popular, that the two on the passenger side are for the A.I.R Diverter Valve and that the other one on the driver side is for the Charcoal Canister Purge Solenoid.
