    You can get the harness from Painless or Nelson. I suggest Nelson. You'll of course need the PCM and such from the LS based engine, and I suggest going with a 4L80e instead of the 60 that will be mated to the majority of LS engines.

    Okay so i have been going over my 302 equipped truck. I have Ran into a problem. Somewhere along the line ford decided to have a speed o meter to get its signal from the rear axle also it makes the truck have an electronic speed o meter. Now to take care of the problem i can buy an aftermarket speed o meter but the gauge panel is extreamly small in these trucks. here is an example




    My Other concerns are the transfer case weither it will bolt up or not.

    Why not just get a functioning speedometer from a junk yard ?

    well my speedometer works right now but once i swap over to an ls1 from the 5.0 ford mass air flow engine i think it will mess my speed o meter up.
