i dont think the plugs just go in...any rewireing i have to do? something custom?

please help

the y8 manifold has sensor on top of throttle body and on the rear of it.. it also has a sensor on the back of the intake manifold

 

The one ontop is the Map sensor, The one behind the map sensor is the Throttle position sensor (tps) The other one on the back is the eacv. And im guessing (not sure)theres another sensor on one of the Intake runners which would be the intake temperature sensor( little white thing) /.

 

yes sir, im sorry there is another one on the runner

 

all of those sensor have to be plugged in?

can i do it with my obd1 harness?

 

yeah dude, The TPS, Eacv, Map sensor have to be plugged in, You can run without the Iat sensor though until you fix it. Yeah use the obd1 harness, just make sure you get the correct manifold and not the automatic intake manifold.
