For the fuel gauge, you need to buy a fuel gauge that reads between 8-12 ohms full and 70-73 ohms empty as that is what Ford used up to 1986. So most of your fuel gauges come in different ranges so they can be used in the various makes of cars, and most will sell this range for Ford.Zorm wrote:Awosome! write up and great pictures. The relays are a great thought, plan on doing the same. I just picked up my 600 dash off fleebay for $35.00. Guy had it listed for a 65 F600, looked at the pic, then found 65 600 dashes on google, not the same thing, so I bid and won!!!! Ok, so you have all electrical gauges correct, what gauge did you use for fuel level? I now those ones can be tricky, depending on how the level is read with the stock gauge. Another question, my 600 dash came with a stock tach, anyone ever tried to incorporate that with out trucks?
thanks.
As for the stock tach, you can only use it if you have it converted. The stock tachs were all mechanical and were for diesel trucks. Our trucks did not have a stock tach option and need electrical componants. But there are companys that can do the work for you and give you a working tach, but it is not cheap. I have used redline gauge works for several tachs over the years and I know plenty of others that have as well. They charge $200 to convert the tach over, but they do an awesome job and you get all brand new insides with the old tach on the outside. Here is a link to their site: http://www.redlinegaugeworks.com/
CNM67 had his stock tach done there as well and it works perfectly with his 390. Here is a thread talking about the factory tachs with pictures of CNM67's tach: http://www.fordification.com/forum/view ... 84#p635684
