    I’ve got two trucks, one is a ‘89 c1500 Silverado with the TBI 5.7l and my other truck is a ‘98 c1500 GMC Sierra with a new 5.7l Vortec. I bought the Sierra with the intentions of swapping the engine and tranny to the ‘89. They are both 2wd with automatic transmissions. The ‘89 is standard cab stepside truck and the ‘98 is and extended cab truck. The computers are different, the 89 is obd 1 and the ‘98 is obd 2. My question is, is there a conversion kit out there that would prevent me from having to rewire the entire truck? Surely this has been done.
