Re: engine harness

Re: engine harness

okay found this from TPI Parts

the green one says (Air Port Connector, 87-92 TPI, 88-92 TBI)

the blue one is for Air Divert Connector, 87-92 TPI, 88-92 TBI

but again where do they go and what exactly are they talking about

DaySHa..........if you have pic's that would be awesome

Re: engine harness

They went to the A.I.R. diverter box near the passenger valve cover

When removing emissions equipment these are unplugged and hidden in the bay
Signals are sent to the connectors to engauge the box but not returned to the ECM so you wont have to change anything other than leave them unplugged
