I am in the process of rewiring guages for a 89 130 v4. Need help! The guages appear to be wired incorrectly. I know they are somehow tied together by color..blue to blue..ylw to ylw..blk to blk..etc. The original multi wire connectors are in tact but the harness that has a black, yellow and green appears to be wrong. Just need a diagram showing how to tie the guages (tach, temp, voltage, water pressure) together correctly. Any help will be greatly appreciated.
