howdy everyone, i know thi sshits old but anyone know any sites to help me with the wiring? I know i need an Si harness anythig else? oh yeah im putting an sohc Si motor in my Dx.... thanks

 

u dont need a harness.. u just need to do the DX to ZC wiring harness from hybrid honda.. they go step by step really easy.
just did it like 4 days ago
PM me for info or instructions and ****

ok thanks, what all do i need though? just the Si engine harness?

 

You dont need the SI harness you are converting your DPFI to MPFI right?? Then all you need is the injector plugs and the resistor box and the plug for it(at least the I used the plug) Dont forget the TPS on a DX is backwards to the SI and other MPFI you will need to swap the green and yellow wires around. When you buy the SI motor it should (hopefully come with a engine harness)IF so then it will have all the plugs you need and try and get the resistor box for the car the motor came from if you can. But any box will work even the ones from the 90-91 tegs and I think some older accords too not sure but I know the 88-91 SI and EX had this resistor box.

 

ok so check it...i got the motor today, and the harness, and the ecu.....do i out the dx on the Si motor? or the si? all i would need top do is extend the wires to the ecu right??

 

dont be a tard like me and mix up b10 and b12 on the pins... ones the cylinder position sensor and like tdc sensor or something.. my car never ran right... ran like **** (used to own a 91 dx with b16) and i never even got the full effect... it ran like ****!!!!! arghh

 

cani just pu tthe Si harness on the Si motor, and like extend the wires from there on????

 

anyone? haha

 

i have to move the wires from C2 to B12. the instructions from hybrid-k.com say "some cars already have a wire in the b12" but it doesnt say what to do if you have the existing b12 wire. I have a wire in the b12 so what do i do?

 

nuttin
i just cut that cable off and took it to the dizzy....

 

The Si engine harness will not plug into the car harness on a DPFI (DX or STD) injected car. You will need the injector plugs and distributor plugs from the Si harness though. All you need to do is use your DX harness and convert it to MPFI which isn't that bad. Since you have the harness you can use it for the plugs and wires you need. I had to do this when I swapped a 96 B18B1 into my 91 CRX DX. I bought the Si harness thinking it would be plug and play but found out otherwise.
