Does anyone have a write up on how you installed it? I have my in, sort of, I have the green light, but can't get it to give me a signal. I have tried all the out's and have messed with the jumper things. I cut the green wire and ran the wire closest to the tcase to the signal in then ran another wire to the other end of the cut wire and placed it in to out 3 with the jumper 3 on, just like the instructions said to. Well at this point I try and start the cal, I have a steady green light but when I roll I get a flashing green. According to the trouble shooting I'm in the wrong out #. I shut the truck off and swithched it to the next one. Same thing solid green to flashing when moving. So again, shut her down and moved it. I have done it to all the outs and have gotten the same thing everytime with no speed reading. Any insight would be great. The unit I have is a SGI-5B.
