So the refurbish for the 73 914 with Chevy 350 is now at the "What is this Mess?" Stage
Wiring in front bonnet area looks great - but once it goes through the "fire wall?" not sure what you call a front bulkhead? The wiring really takes a turn for the worse. The owner got a new to the car complete harness with it. It is a used harness that was removed from another car pretty much intact. The only real issue with it, is that some of the wires were cut with a cut off wheel. The area is where it came through the rear bulkhead. Plans are to use the 12 wire plug wires for the engine and gauges, some for what they are for. Wondering what others have done? Any help will be gratefully accepted. (IMG:style_emoticons/default/cheer.gif) I found wires in the car that went no where just attached and cut at both ends. Some pictures of the wiring: After new used harness was unwrapped and inspected, I rolled it up and set it on the floor of the passenger side of the car. Went into the house and had a medium old guy panic attack. (IMG:style_emoticons/default/confused24.gif) A couple of weeks later I started to tackle the new harness - laid it out of the table and had at it. I made a 4x8 table out of a sheet of plywood and covered it with cardboard, then laid the harness out for inspection. I started tracing wires to see where they went and inspecting for cuts or bare spots. I removed the factory fuse panel as the car has a bigger blade fuse style panel in it. |

Question : What tach are you running - or can the stock one be revised to work with a V8?

Question : What tach are you running - or can the stock one be revised to work with a V8? Ok then maybe you may need to replace it ,but your issue could be its reading the wrong signal which is most likely,try the adaptor first and see. Porsche tach's received 2 different voltage signals year dependant,cannot remember which is which but the signal from a V8 will be all wrong what ever voltage input and of course upset by 8 signals every rotation . If the needle on the tach you have is even and constant in movement you should be ok with that one with adaptor. |
