wiring
iv'e heard some people have trouble with an auto computer, but iv'e been running my 01 5.2 in a 72 dart with the 904 for 3 years now without any problems, and no, i never hooked my oil sending unit to the computer, so it doesn't need to see the pressure. then again, easy rider never could get his right till he got a manual computer. go figure. lol. mine's a 5.2, so maybe there's a difference in the 5.9. i will tell you this, if you have a factory security system, you'll have to get that taken out. if i can help, just ask. dave.
