When I replaced the outside temp.sensor, I thought I should avoid the hassle with routing the cable all the way into the dash. So I cut the wire close to the fuse box and soldered on a standard 2-pin MB wire plug. Nice solution, but the temp reading did still malfunction. The sensor came from an high milage car, so it may be out of order for what I know. But it strikes me, is this sensor sensitive for resistance variations? Does it need the total wire length to operate correct?
