Until I can afford a Standalone ECU, I decided to revamp my very worn and BRITTLE TII Emmissions harness (Engine). The exisiting harness covering was missing/brittle/worn beyond belief. The injector connections were trash.



The goal of this endevor are:

a. Replace all broken connections

b. Replace all brittle wiring

c. Remove all un-needed connections (ie "Rats Nest Wiring")

d. Protect the wiring from future damge



In the past 2 evenings I have the following progress.



1. Removed existing harness covers and wraps. Temporary Tie-wraps are used to maintain harness branch locations.

2. Solenoid Valve Connections and wiring have been deleted from the harness back to the ECU plugs



This has resulted in a large quantity of trash by the workbench.



The next stage is to place the harness on the engine to determine optimum routing and branch lengths.



Then the individual runs will be replaced with Tefzel Mil Spec Wire MS-22759/16 and new connectors. The branches will be wrapped in High Temperature Silicone Tape. Then a vinyl protective cover will be placed over it.



Pics to come soon



Connectors and Pins hi-lighted in yellow have been BANISHED from the harness

I am changing the routing of the Injector/Throttle branch so it no longer goes near the exhaust. Its not a matter of free time, Its a matter of my cars never get finished

Here is he pile of CRAP I have removed so far....

its amazing how much harness is "extra" you might want to double up the ground wires, just a thought

Here is the new location of the injector resistor pack. I have also relocated the boost sensor and he mixture adjustment...
