ok... i know what you guys are thinking... another noob that didn't do his research... ok... i am another noob but this isn't the same question as everybody else... i just want to know if anybody has every tried plugging up the SI harness to the DX dash harness? is there really that big of a difference in the harnesses? i mean... can't you just move the two wires and add the two that are needed and everything should be plug n' play right? i know everybody says to just cut it up and splice em but i just don't want to rule it out and cut up a perfectly good harness before actually making sure...


CRX DX d15b vtec swap in process of wiring

 

I'm sure someone has already thought of that, tried it, and deemed it
an inappropriate method of conversion.

-But if not, you could try it and report back your findings

 

alright... cuz my brother already gave me the idea of just hooking it up and then reading the codes... if anybody else has tried it let me know before i end up shorting something or messing up a plug haha

 

they are way different. You will have to repin most of the wires on the strut towers and it wont add the extra wires that you need to the inside of the car. It's easier to convert the dx harness to SI. And don't forget about the wiring changes at the ECU.

 

i was looking at the wires by the fuse block in the bay and all the wires look to be the same... but i have all the plugs in right now and me being my hard headed self... i'm gonna see how it goes... i'm not gonna try and start the car or anything but i just wanna see what codes i'm coming up with... thanks

 

hey blakarakynd let me know how this step works out. looking forward and a ZC swap for my std and i want a OEM look when im done with the wiring. thnx bro

 

there is no way around the mpfi conversion unless you swap to the si interior and exterior harness.

 

haha yeah... you guys were right... but i do have another question and i'm hoping you guys are able to help... if i decide to run without a resistor box (i have a whole bunch of high impedence injectors but only 2 lows =P ) what do i do with the wires that are supposed to be going to the resistor box?

 

just to let you guys know... it wouldn't fit like oem because the stock dx harness had extra wires on the plug above the shock tower... so the plug ended up being bigger than the si harness.. yeah.. i just didn't want to deal with finding out what goes to what and what belongs where...

 

anybody??? nothing?
