I recently bought a DFI unit from a guy thats wanting to upgrade to SpeedPro. I was wondering if there is a company out there that makes a harness that would integrate the DFI unit into the factory ECM so that I can retain the factory wiring harness? Sure seems alot easier than pulling out the fact. harness and putting in another harness. Also........what functions would I lose if I run the DFI stand alone (speedometer, criuse etc)? The car is an 88
TPI 350 w/ Mass Air. Any help is greatly appreciated.

 

Go to www.whiteracing.com or www.fasttrackperformance.com . Either of those places have the adapter harness to plug in your DFI into the factory harness. Hope this helps.

 

Thanks man. I went ahead and ordered from Dan at White Racing. Should be here Wednesday.....I'll install after work. The DFI should make a ton of difference. I'll let everyone know how much of a difference it makes.

 

You can ask the guy who you bought it from if he ordered it with other options like ESC(knock sensor wiring-really helpful when tuning for ignotion map) and cruise control. I got mine back in mid 90's and I had to pay extra for those 2 options.
