ok i bought an accu-speed jet perf. box to correct my speed-o-meter.hooked it up exacly how the directions say.went for a test run and nothing adjusted,also abs light came on but abs still works.so i called up the company and told them my problem.they said to conect to a pink wire with a red strip because its rwabs only.so i did this and nothing again.called up the company again and they told me to send them the unit,so i sent it back and got another one.re hooked it up and still not working.so i went to a truck place and had one of the gurus look at it and made him scratch his head.anybody know why im having this problem/help needed?
