did dpfi to mpfi conv., everything works right except the parking lights and reverse lights. fuse is fine. you dont need them to be legal right?

 

u did somethin wrong. reverse lights u prolly left that sensor unhooked its on the trans, 2 wires. but the parkin light are also ur tail lights. do those work? if not then thas illegal. and long as u have headlight tailight blinkers and brake lights ur set.

 

you can unplug the reverse light switch at the trans and touch the 2 together and see if the light comes on. this way you will know if you just have a bad switch, remeber the key must be on of course!
