I have an extremely custom built wiring harness to use a Turbo motor in a 2nd gen minivan. Harness was custom built for a local freind to use a 2.5/568 in his 93 minvan with an accompanying calibration done by TU. The harness has been built to plug and play any T1 or T2 motor. Harness also has provisions built in for an egt gauge, boost gauge, oil pressure gauge, charge air temp sensor, has two temp sensors for the intake charge (one for pre ic air temps, and one for post ic air temps), voltmeter, water temp, oil pressure, daws device a/f meter, and 2 gen radiator fan plug. The calibration was built to run a 2 bar map with +20 injectors at 15psi, advanced timing, revises fan schedule, removed fuel cut off and rev limiter, also removed the annoying a/c compressor shut off when car is in wot.
This harness is a plug and play setup. A TON of time was spent on this harness to make it work properly. The finished product looks almost stock in black wiring loom wrap. Included with this set up will be a set of Westech analog gauges for this setup (egt, dual reading air charge gauge, volts, water temp, oil pressure, and a/f)
I have tried to tell you everything I know about this setup, if you have any questions please let me know and I will try to answer them. This web site has a writeup and a few pictures of the van that was running all this stuff.
