i resently purchased a 91 crx hx, it has the single cam non vtec with an automatic trans. i also have a 91 teg which has a complete b-18a swap in it. well installing the engine isnt the problem, the problem is wid the wiring. i plan to use the PR4 ecu but when it comes to the wiring harness i'm lost. if i'm not mistakin the hx has only 2 injectors and the ls has 4 so i'm wondering if i should buy a harness from a company or will the stock ls wiring harness plug in . also will i need an adapter to put the PR4 ecu on the car. oh also i was wondering since i'm going from automatic to 5 speed will the gas/break/and clutch pedels from the ls bolt up in the crx. thanks

 

Wow. i haven't heard of HX CRX before. It must be a few made only.

 

my mistake, its an HF i hit the wrong key when i was typing.

 

Hf has 4 injectors like the Si so you are pretty much good to go. The stock integra harness will not plug in. But the pr4 ecu with clip right in with no mods.
