I just bought a microtech lt8s and started hooking it up but i am having some trouble with what to get rid of wiring wise on the stock harness if some could just tell me which color wires to keep off the stock harness and what connectors that would be great

sorry if this question was already answered on here before I tried searching but could not find what i needed thanks

s4 harness with s5 motor

i'd lose the harness completely.

use your injector connectors (unless you got new ones), coolant temp, and air temp connectors.

you can wire it up to the cas at the sensor, but i prefer to wire that part into the factory harness (front harness). that's the one connector you pulled from the stock ecu that you don't remove with the engine harness.

other than that, it's pretty straight forward.

yea, or you can do what I did and remove the clip from the stock harness and connect it using the MT leads. the rest you can throw away. The oil press, coolant temp, and rpm are all on the body harness.

when i pulled the stock engine harness it had 2 connectors that go to the ecu and these 2 orange looking ones (one of them has the wiper motor wires going to it) am i just going to cut the rest of the wires off of the wiper motor connector and do I need any of the other wires in the other orange connector?

p.s. where would be a good place to plug the vac hose from the MT , any where on the intake manifold?

thanks for the help so far

just slit the insulation from the harness. the wiper motor harness will pull right out, but you might have to pull a pin or two, then reconnect them--they're tangled sometimes.

either way, no biggie. the wiper harness is in its own little world--even though it's loomed with the engine harness.

also the exciter wires are on that plug. The two wire from the back of the alt.
