The Haltech wiring harness is quite long, and for most of its length, the wires are unprotected. Since the wiring will be exposed above the transmission, I decided to use heat shrink tape for protection, using approximately 3 to 4 feet of it. The two dangling cables are for the CAN bus and the wideband O2 sensor, which I will also need to extend and protect.
I routed the wiring through the engine compartment on the passenger side. Are there any potential issues with this route? There's a lot happening on the driver's side, so I'd prefer to avoid it. I still need to shrink or trim back the last few inches of the heat shrink tube.
I'm using the opening in the tunnel that the throttle rod previously passed through for the vacuum line to the ECU. I installed a new rubber boot on it. Additionally, I drilled a hole through the passenger side of the tunnel and added a grommet to route the vacuum line to the ECU.
