Next up is wiring. One of the things I truly suck at! Scouring the internet gave me a few ideas on what I needed to keep from the v8 harness, pondering the minuscule harness on my tdi defender, and the help of a friend who’s gone the swap already, I began.
The V8 engine harness is massive, all the injectors, sensors, emissions, and sending devices are pretty overwhelming at first.
The reality is, the tdi needs about 4 wires to run, fuel solenoid, ignition and starter being the primary things. These were fairly easy to pull from the harness, and a few ignition wires were repurposed. Factory temp sensor, oil pressure sensor, and tach sendor was reused, which should give me full gauges in the truck.
On the d1 the elm is under the hood, and all major wiring connections too, essentially unplug the Ecuador, throw it away, label the wires required, and start hacking away! Once the loom has been paired down , extend what’s needed to its new spot, route everything cleanly, wrap everything in wire loom.
I have not yet figured the wiring for the A/C. That will come later
The other harness is the tranny. You need reverse lights, xyz switch, and VSS for the speedo, The xyz switch needs to,be bypassed to power up the starter circuit. Several methods have been done, i chose to ground the black red wire in the passenger kick panel. It works!
