Yeah. Don't use a self drilling screw into the support for the radiator without checking to see if the loom is on the other side. It just nicked a tan wire and was enough to cause a dead short that was virtually untraceable. We were mounting the two relays for the after market headlight relay harness. The leads were too short for both headlights so we cheated and installed the relays as close as we could to make the wires be long enough without splicing. The icing on the cake? The harness was no good either, right out of the box.
We spent about 20 hours with Kendal's, Bob's and my time running tests looking for shorts, disconnecting modules, disconnecting pigtails to the taillights, and front cornering lights, headlights, etc. We even removed the seats and redid the splices on both sides. And then removed the dash and traced wires from there, which is how we found it.
It was a bitch replacing the dash because we had on pigtail that had a 8 pin female and three pin mail but was a perfect match for each other. Turned out to be the Bose 3 pin pigtail not the Reatta pigtail [remember the Reatta uses a lot of parts from the Riv] so it burned up the stereo [at the drivers side rear as it gave power to the speaker wires because Bose speakers are powered]. Fortunately I have an extra stereo in my parts bin and can be running tomorrow.
But what a nightmare. All for a defective after market harness and a self tapping screw in the wrong place.
