I'm making steady progress on my conversion. The engine and transmission are back in place, and the axles are securely torqued down. It's much less cramped now without the CIS system.

The Haltech R3, which also functions as a PDU, offers several features I'm eager to utilize. For example, the fuel pump is directly connected to the R3. I routed the wire through a grommeted opening near the pedal box. Additionally, I can use the R3 to control the starter solenoid. I'm considering adding a momentary push button for this purpose, but I want it to be discreet, so I'm still deciding on the type and placement of the switch.
I'm also figuring out the remaining wiring. There's not much left to do back there—just a few low-current loads like oil pressure, oil temperature, and reverse lights. I'll probably use a new Deutsch connector for these.
Does anyone know what this yellow wire is for? It comes out of the original harness, goes into a male/female junction, and then back into the harness.
