ok so im new to all this, but i got a b18c1 and i want to put it into a 97 civic dx chassis. what engine harness should i use? the d16y7 or the b18c1 harness?

 

i say the b18c1 is the best to go unless u want tog et all the other accessories for the other harness. cut and splices ecu chippings.

 

Im guessing a hx harness would be good. because it will come all the plug you will need.

I could be wrong.

 

use the civic harness. the integra wont plug up to your civic, the civic engine harness is a 1 piece that connects from the ecu to the engine iirc. youll have to add iab and knock

 

get one from an EX or Si, they'll save you some trouble in having to cut and re-wyre stuff (i used the stock harness from my ex when i swapped in my b18c)

 

civic harness with these changes super easy..... http://www.ff-squad.com/tech/wiring/wiring.96-98.jpg

 

If you're on a budget use the DX harness with a subharness for VTEC, knock and IABs. If you're willing to spend a bit more get a 96-98 EX manual harness and then wire up the IABs. You won't be able to use the Integra harness unless you really feel like doing a lot of wiring.

 

Use an obd2(A) ex harness 96-98 civic. Simple just extend your IAT sensor plug, and your vtec wires. What year is the motor? What ecu do you plan on using? These are very imporant for wiring as well. Will you be utilizing a Crank positioning sensor as well? USD/JDM?

 

1997 gs-r motor usdm, and i was planning on using an obd1 p72 ecu or a p28 from rywire.
and i was planning on utalizing the crankshaft position sensor as well i just wanted to know the easiest way to wire it in would be cause the harness that came with the car was just molested to ****..

 

Easiest way to wire without a major headache, would be use a 96-98 civic ex harness.

Extend vtec and IAT sensors if needed. Everything else should be plug in and play. If you're using an obd1 ecu, I don't believe they use check for knock, however you will need a jumper harness (obd2a to obd1 ecu). p72 will engage butterflies as well.

 

P28s don't, P30s, P61 and P72s all do.

Op if you're planning to use an OBD1 ECU get a '96 - '98 EX harness and save yourself a lot of trouble, don't worry about the CKF sensor, the OBD1 ECU wont look for it anyway.

 

so will the civic harness plug into the p30, p61 or p72 directly or do i need a jumper harness?

 

You need a jumper harness. If using anything other than a P72 you'll need to have the ECU chipped and get a tune (at the very least a good P72 basemap)
