Help me install!!!!
 

the ignition/coils colors dont match up!! which color goes with which?

and also, which water senor do i use? the one at the top of the coolant filler neck
or behind the coolant assembly

please help me quick! im sitting here waiting for the reply!

I have the same problem over here. I belive the colors dont match up because I have the LTX8 unit. The book says all the ignition triggers are Grey wires with various colored stripes. My harness had Yellow, Yellow/Black, Orange, and Orange/Black.

I just followed the wiring diagram in the back of the manual.

LT8X:
Yellow - Leading 1 (negative side)
Yellow/Black - Leading 2 (neg)
Orange - Trailing 1 (neg)
Orange/Black - Trailing 2 (neg)

I hope this diagram is right!!!!

The coolant sensor is the one on the back of the water pump housing. The connector type is just about like your fuel injectors, but you may have to grind/file the slot off from the sensor so the connector will fit on.

Well, we've got to know into what you're installing the EMS! :)

You need to connect the pink and green to the fuel pump relay, according to the wiring digramme

Dale

but on the fuel pump there are 5 wires, which one do i splice into?

i don't remember the exact pin outs for the relay but you use 4 wires
a 12v constant, pink, green, and then the wire that you run to teh fuel pump. I ran this wire all the way back to my car i think it was a 12gauge wire from teh battery to the relay ect. on the fuel pump i just wired the 12v to the + on the fuel pump.

Make sure when you look at the color of the wire you're looking at the wire that is connected to the sensor or coil.
