TPI Conversion Progress/Process - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Captkaos** · 08-26-2005, 11:42 AM

This past weekend I started working on the pieces required to convert my '78 Jimmy to TPI. I had purchased an SLP TPI harness back in '95 that they were clearing out and had it sitting around for a while. A while back I picked up a TPI intake, MAP setup and Distributor. Well plans have started moving forward to convert the truck (I HATE carbs..)

Wednesday: recieved the new Blazer EFI sending unit from GM

Thursday: ordered fuel lines for a '90 Blazer -not here YET

Friday: ordered: Sensor kit, 127749 ecm (turbo app ECM), 350 TPI prom, stainless steel bolt kit, and throttle body gasket kit and it arrived on Wednesday.

Saturday: started laying out the TPI pieces and started cleaning them up.

Now that the ECM is here I can start repinning the MAP harness from SLP so it can plug into the 7749 ECM and function properly. This should be fun.

There are a few other odds/ends that I need, but progress has started.
