the regulator or the timer? for the FPR you just cut the stock fuel return line and run it into the inlet on the new FPR, and then connect the new FPR outlet to the stock return line. then hook a vacuum line to the top and you're done.
for the timer, unplug stock harness (on steering column), plug in HKS harness, and plug timer into HKS harness. ;D
Wow the timer is that easy? NICE! ;D As for the fpr, did you keep your stock fpr? and run the new one after it? Or did you eliminate the stock one? Let me know thanks
