As promised, this post will document ECU wiring. I will be wiring in a Link G4X MonsoonX in a “piggyback” style. Below is a wiring table on what I plan to do.
I have seperated the loom and marked the cam and crank sensor. There will be some figuring out to do on the cam and potentially crank signals as I know they differ from the ZC32S (which Haltech has documentation on).
Unfortunately, there is very little information on aftermarket ECUs in these cars and a lot of people report odd issues with cheaper options like AEM and GReddy E-manage (E-Mangle).
I’ll also need to decide what I do about the variable intake runners either:
a) try to remove it
b) replace with ZC31S intake (may require further head drilling, new intake piping)
c) use the Link to control it (looks doable)
If you made it this far, below are images of the ZC32S ECU wiring for your reference. I found these extremely hard to find, hopefully this helps others. I cross checked a lot of the wire colours and it all aligns, will need to check with a multimeter to be sure.
