ok I got an 88 dx shell, had a turboed b16 in it so the wiring harness is really hacked (kid actually did a nice job with it though to the previos owner) but I am swapping in a 91 dx dpfi motor...I was tryin to fix the wiring harness back to dpfi but the only thing I had to compare it to was my 91 harness and the colors/pins just weren't matching up so I am just gonna put the whole interior wiring harness from the 91 in the 88...I have noticed some small differences already but my main one is the 91 has 6 wires going into the door while the 88 only has two...can I just use the 88 plug and match up the two wires that were on the 88 (one red one black) or will this not work and is a bad idea and I should just stop right now and try and fix the 88 harness?

 

not really going to help ur wiring issue...

but why do you want to wire the bay back to dpfi? most people CANNOT wait to upgrade to mpfi (1 including me) unless ur going the economical/gas milage route then i dont know why ud wanna switch back to 2 fuel injectors.

 

well got shell for 200 bucks and have a totalled dx...don't want to spend a lot of money here...just want to make her run......

 

Spend 200$ and get a D16A6. Plug and play and it will have 16 more horses under the hood.

 

I actually completely rebuilt this motor because I was plannin on making a very reliable good gas mileage car to take across country but now I got a new car so I don't need this one anymore so I just want to get it runnin and out of my shop

 

Send it to me asap swak bby b01

 

bump I need to know if this will work or I am wasting my time and should go back to tryin to fix my hacked harness

 

why dont you just reverse the mpfi wiring changes? It wont be hard to put a dpfi harness in the bay and return the pins at the ecu to stock ....

 

well you can email me i have a pdf version of a dpfi and a mpfi engine computer pin out so drop me a line at brad@brcoxmail.com and i will try to help !!!

you don't have to change the interior wiring harness. like the said, just reverse the changes made to make it mpfi and that should do it. try to locate a dpfi-mpfi diagram and go from there, there shouldn't be to many wires to change back. I don't have any diagrams handy otherwise I maybe able to walk you through it.
