First of all I dont have my stock wireing harness anymore.

I wanna install a Haltech E6X, I have the ECU in my glove box and my battery in the rear compartment. I am ready to start passing wires. But I need a few answers first.

I have 4 low impedence injectors. Should I change the 3A fuse to a 10A, 15A or 20A fuse ?

I`m running a walbro fuel pump. Do I have to wire the fuel pump relay from the Haltech to my fuel pump or can I just leave it as is wired to the original harness ?

My Leading coilpack is wired to an MSD 6T. How do I wire that up to the Haltech?

And the trailing coil pack is it only 2 wires that splice to the haltech harness ? If yes which ones ?

1. The haltech owners manual answers the fuse question.

2. in my FC, the relay with the haltech is connected to the original harness AFTER the OEM fuel pump relay. mine is connected right before the connector on the fuel pump. that way i can remove the fuel pump without having to cut and resplice it every time.

3. i've never used MSD coils. but the factory coils only have 2 wires. 12v power and ECU signal. if that helps.

4. the trailing coils has 3 wires. 12v power, ECU signal, and a toggle from the ECU to switch the coil pack between the front and rear coils. (99% sure of that)

on the hitman web site it says only 2 wires on the trailing coil pack, pink and white. What's the 3rd wire ? And to which wire does it hook up to on the haltech harness ?

i believe it's the green wire. (aux out) it's for the toggle switch, you can also connect the yellow wire from the trail coil to the tach.

The 3rd wire is 12V+ switched. You can either use the ignition power output from the Haltech or simply leave the stock harness intact to supply switched power to the coils.
