i converted my 3.5 v8 landy to a 3.9. after alot o messing around with electrics an extending the wiring harness so i can put the ecu behind the passenger seat i cant get the alternater to work. its a new unit. do i need the battery warning light to be wired up to the back of the alt to act as a switch or can i just bypass it some how. just want to get it working not that fussed how it looks or how it works as long as it does
