Hiding Front Engine Sensor Wire Harness

["Dart67"]

I started this project yesterday 10/10/2025.

I made 2 flat brackets and 2 studs to mount onto the passenger side of the oil pan.

These 2 brackets will serve as supports and a place to secure the wiring harness I just made. The harness has connections to the factory temperature sensor, EFI temperature sensor, the Cam Position Sensor. and MSD Crank Trigger. This harness will go to the back of the engine over the transmission bell housing then pass through the firewall into the passenger compartment to the EFI ECU.

I did this to hide as much wiring as possible from view.

Powder Coated brackets

Studs install on pan

Brackets installed on studs

Wiring Harness installed and secured to brackets

Harness connections to sensors.
The Gray and Black thing is the Cam Position Sensor, The Chrome Acorn Nut above it and below the thermostat housing is the Factory temperature sensor. The Red wires to the right of the Cam Position sensor going into the black plug is the EFI temperature sensor. The Blue AN Fittings are the heater hose connections.

Looks very tidy- although I would be a little concerned about the harness rubbing or contacting the centerlink and or idler arm in that location. Might warrant an additional shield to protect/route the harness a bit higher in that location?

It will be fine. If the center link and idler arm get that high up, I will have far bigger worries than the harness. If you look at the first photo of the bottom of the oil pan, the idler are sets over a 1/2" lower than the notch in the pan.
