Hi I need some help!! I've done a 3800 SC swap into my 87 FIero ,the harness was done by FieroFlyer good job!! My problem is that when I originally started the project it was going to be a modified Fiero but I have gone in a different direction and am doing a 308 Body. I've installed VDO gauge package but am having some problems with the temp gauge VDO has their own temp sensor that goes into the stock position with only 1 wire to the gauge. The problem is it is not sending a signal to the fan relay to kick in. any ideas how to get it to work properly.
