<> white wire green stripe:Ignition found at FL035   Solid Black:12v Constant found right in the middle of fuse panel. White wire red Stripe: Starter Inturupt found at FL037  now the only tricky part was that,because of the button start there was a pulse at ground to our unit.if corrected that by installing a relay to stop the pulse ground as follows: on boush relay 86 to Ign(WHITE/ green)  85 to ground,87 to our Ign wire and 30 to 12volt constant.  all this is under hood driverside removing  2 plastic covers and removing fuse 2 harness bolts and turning it over all wires are underside  pleanty of room.."throw it in the gutter and go buy another"
