I have an 88 GT that keeps blowing fuse 18. When refused the tach will come back but will blow the first time I hit a bump in the road. I'm sure I have a lost connection or wire going to ground. Any suggestions on where to start? Thanks!

This is from my 83 " Electrical and Vacuum trouble shooting" supplement
18 supplies power to all of the tad/tab system... Also the Tach, low fuel warning, and seat belt warning indicators.....
On an 83 it also supplies power to the WOT A/C cutoff system.....
Remember this is from a carb system where yours will be FI. I want to think that some of these will be the same??
