Well i got the harness and all, injectors are converted to MPFI..engine harness is in,
but got some mystery plugs,
one..the one that connects the engine harness to the interior? harness on the drivers side, the plug will not go in, there different sizes? couldn't find anything to solve this issue..looked at wires between the harness i pulled out, and the one in it has more wires.

and on my other harness i had three wires coming in(well four counting the power for the fuse box) the main engine one(big circle one) rectangular one and one other small circle one, on this harness i dont see this small circle one...sorry i dont know the names of the plugs, but straight up dont know the names.

there is more plugs, but that is the main concern of mine right now...
the others i will figure out,

 

whoah whoah whoah!

you're going MPFI to DPFI?
or DPFI to MPFI ?

 

haha whoops my bad..better change that. yeah yeah DPFI to MPFI

 

so you're using an si engine harness?
have you tried the search button? we get about 2-3 threads like this a day and all questions have been answered. not being a dick but try researching it first because 98% of the time the concerns you have, have already been answered

 

no i am using a 88-91 DX harness...i am swapping in a LS motor, and i will try to search, but most get lost or i get a load of garbage posts.

 

it would be much easier if you got some pics up. I can help I just finished doing my conversion.

well its dark here now, so i cant get any pictures right now.

 

it sounds like your using the wrong harness for the car since the engine harness wont plug into the body harness. you need to use the stock engine harness for the car then convert that harness to mpfi. what year and model is your car? and what year and model is the engine harness your trying to use?

 

the engine harness i have is out of a 89 DX and my car is a 91.
pictures below




and we re-tried my old harness, because i noticed some loose grounds when i was taking it off, we put te other harness back on, and same problem. am not getting any spark. and we have changed out dizzy(brand new) and plugs and plug wires...
BUT whats one thing funny about this CRX, is there USE to be a LS swap in it..than ran and drove..so idk if the 2 owners ago swapped the interior harness? or what? its messed up for sure.

 

how is this helpful???

 

just use the stock harness that was in the car and just add the necessary wires for the mpfi...look it up in the faq or just google it, it should take u about 2 minutes to find a write up

 

YEah but see now...is hte INTERIOR HARNESS WILL NOT PLUG INTO THE DPFI HARNESS THAT I BOUGHT! AKA it will not turn over AKA im not gonna waste my tiem converting a harness to MPFI if a main plug does not plug in.

 

Looks to me like they swaped out your interior harness. My dx engine harness looks like yours mine is a 91. If you really want to make it work you can cut those mismatched plugs off and splice in another one.

 

well looks like i am gonna try and swap plugs....
