I got a used 3.54 speedo calibration box that has Unitrax sticker on it. Looked in tech section here and in the Alley and cannot find install instructions. Any help?
OK have a problem. Fellow poster e-mailed me instructions, Unitrax was nice enough to fax me instructions, and both of these matched the above description, however, my box has the following color wires: yellow, white, brown, blue, black and red in that order on one end, and orange on the other end (the brown wire was actually bunched up inside the case and not even sticking out). So ihave 6 wires instead of four, and the colors do not match Do I have some sort of old unit or something? I took the lid off and the wires are not spliced so that is not why the colors are different.The center PCM Connector should be White. Remove the cap and find Pin # 27, the White W/Tan wire. You need to cut the Wite W/Tan wire and connect the Blue wire to the end that still goes to the PCM, connect the Green wire to the other end which goes to the speedometer. The left PCM connector should be Black. Remove the cap and find Pin # 2 a Dark Blue W/ White or Gray Stripe wire, DO NOT CUT THIS WIRE just Splice the Red wire to it. Black goes to ground.
