Replacing Brittle Wire Loom on a 4.0 Engine

While cleaning the throttle body, I discovered that the wire loom protecting the wires is brittle and breaking apart. I'm concerned about potential damage from engine heat. Has anyone replaced the wire loom on their 4.0? If so, what high-heat materials did you use? I just ordered some high-heat tape and wire loom from Amazon and would appreciate any advice or recommendations.

Go pick up a cheap pair of "safety" scissors, the kind for kids, with the rounded ends. They will make trimming off the old loom and tape much less nerve wracking.

Disconnect your battery and do each leg/bundle one at a time by disconnecting the end and starting there. Re-wrap each leg as you finish it, reconnect, and move to the next one. Go slow and careful.

When you get to a clip or bracket, be ready for tabs/studs/etc to break no matter how careful you are and replace them with zip ties or insulated "P" brackets, like these right here (illustration purposes only, get the right size). Don't mess with the OEM heat shield tape (the aluminized stuff), it's on there good and a real pain to replace.

 

Thanks for the tips. I cleaned up the area this morning and added the loom along with the Tesa tape. It was some work, but it looks good, and I feel better about it now. I didn’t take any pictures, though. I put it all together and then realized I forgot.
