TII Engine Harness Rewire and Optimization:

Background: My 87 TII Engine harness is toast; Brittle, broken Injector Plugs.

My Plan:
1. Fasten harness to workboard
2. Remove Brittle harness cover
3. De-Terminate and remove wiring associated with removed Emmissions components and Engine Accessories
4. Replace Injector clips and rewire back to ECU Plug
5. Install new harness wrap

Questions:
1. What Harness wrap did you use?
2. Has anyone elese done this (DALE?), What were your results?
3. Did you change the harness routing to avoid the hot spots?

I used 3M #33 tape when I rebuilt the NA harness in my 'vert to a T2 harness.

I suppose the 3M 177 tape (for extream enviroments) would work as well.

Justin, On the branches of the harness I will use that. For the Main "trunk" of the harness it is too small. Of course until I gut the harness I won't know for sure

you could cut the ends out of a bunch of condoms and tape them together....

sorry i couldnt think of anything useful....wait....wait... the light clicked on

go to http://www.terminaltown.com/Pages/Page66.html

look at the silicon tape. when heated it bonds to itself, forming a single tube. and it withstands 392 degrees F so as long as you dont wrap it on your headers i think it is durable enough
