[406 Q-ship]

I did put a L98 (Corvette 350 from the C4) into a 1988 Pickup back in 1988. If yours has what your calling 2 computer modules, that is a harness from a 1985 (one year only). The second module is a injector driver module. The wiring for the TPI engines is much easier than the later engines (LS1 or LT1), it is a completely seperate harness with a few contections. There will only need to have a Vehicle Speed signal. attached at the speedometer back then but now you can get an encoder that installs on the speedo cable. From there the diagnosis connector for the scanner and a check engine lamp (now called the service engine soon), other than getting 12 volts battery and a full 12 volt ignition wiring (in cranking) it is pretty easy. You can looking into using a Howell harness. The computer can not be re-programmed, the chip must be changed if you end up with a computer from a VATS car (1988 and up for the F-body).
