A Worthy Addition
I am the original owner of a '92 Mustang GT convertible which is garage-kept and pampered. Each Summer I do a little extra, and this year was BBK C.A.I., MAF, 70 mm. T.B., E.G.R., and SCT 4-Bank Eliminator chip. I found all of the generic directions to be ineffective, so I had to follow my instincts. The following detail may help the next customer. After popping off the kick panel, the computer was almost totally obscured by a number of multi-wire cable connectors. They all have individually designed connector "shapes," so don't be intimidated. Spend the time to CAREFULLY disconnect these harnesses. The computer was held in place by a very tight-fitting, plastic harness, which holds the computer in place. This harness will be discussed during the reinstall. I was happy to find that my computer board J3 connection was protected with white grease. This made careful board preparation much easier, but this step does require your attention. I double-checked the contact issue with a digital meter to verify continuity. After the SCT board and cable is plugged into the J3 port connection, I carefully taped over anything that could case issues during the reinstall. Now, the plastic harness will not accomodate the computer; because the computer with the added SCT board will not fit into the smaller harness. I was able to use the harness by simply cutting the long plastic strip right above the bottom anchor. I also found that I was able to visually check my work by removing the glove compartment door. I was now able to carefully position the padded insulation behind and above the computer without stressing the SCT board. This additional step also made the reconnection and repositioning of all of the wire harnesses much easier. I ran the cable across the dash to the center console, and I currently have the cable and switch hidden underneath the ashtray, directly behind the floor shift. I will be enhancing the final switch location with the purchase of a bezel. All of the modifications have made a dramatic difference in performance. It's been a good Summer.
