Add EGR Wiring to Aftermarket Harness
I have an aftermarket tbi harness that does not have the egr wiring. Does anyone know how I could add this wiring? Do I just take the red and white wires from the egr connector and connect them to the proper pins on the ecm?

Re: Add EGR Wiring to Aftermarket Harness
That is the EGR solenoid it is connected to the actual valve. The most times The EGR is programmed out of the E-PROM chip in the ECM is aftermarket and performance cases. Know all of this is from memory and that is going back a LONG way to come up with that info.But that isn't as impressive as this recalling the service number for the truck TBI ECM, watch this. 1227747 Boom.[I built a lot of trucks back then]
So saying that to say this I don't know if trying to put the egr solenoid into the system if the computer would even recognize what it is and what it is for |

Re: Add EGR Wiring to Aftermarket Harness
Like hugger said, if the egr has been deleted from the e prom I wouldn't worry about it. But if the ecm has never been messed with, just search the ecm number to find the proper PIN numbers and add them to your harness.

Re: Add EGR Wiring to Aftermarket Harness
Thanks guys. Egr has not been removed from eprom. So just run the wires to the correct pins? No relays or anything like that? I don't know squat about wiring, so pardon my ignorance.

The red wire should go to a 12v ign on power source and the other wire is grounded through the ecm. Look at your ecm and post the number and I can find you the wiring diagram.
