The trailer wiring harness is a well thought out solution. Last weekend I installed a VDO tachometer in MY72BUG. The wiring was mostly very close to the illumination lights and fuse box so this was not a problem. The one long wire that went to the coil was fished down through the same route that the main wiring harness uses to go to the rear of the car. I had enclosed this in one of those ribbed plastic wiring harness covers. For most of the way, I was able to pry open the cover and insert the single wire. The tach looks great. I removed the old speaker grill which is to the left of the speedometer, used calipers to measure the diameter of the tach, scribed a circle with a compass and did the hole cut with a Dremel tool and a few cut-off discs. The "tines" of the old speaker grill grip the body of the tach so no further mounting is needed. Piece of cake. Dan in Goderich
