Hi I am new to the forum! This will probably be a bit out of the ordinary for questions on this forum but I figured there are some pretty handy people out there. I am just about to finish my first gen coyote swap 1979 f150. I bought a set of stock gauges that came in the mustang to complete the look of my custom dashboard. Does anyone have a schematic of the 27 prongs on the back of the cluster??? Realistically I just want the tac and speedo to function which I already have a GPS module for. If anyone has any information it would be greatly appreciated!
