i bought a vtec engine and i used to have a non vtec. how do i wire that in with the ecu. also if i buy a ex harness do i have to wrie in vtec or can i just have it work. cause that would be awesome. the car is a 95 accord lx. with a f22b1 replacement

 

you will need to run wires for vtec. you cant swap out harnesses and have it function correctly without changing both the engine harness and the cabin harness. but its simple run the two signal wires to the corresponing pinout locations on the ecu plugs...and you will need a vtec ecu - which i happen to have on that im selling!

 

why does the cabin harness have to be changed if you go from a non-vtec to vtec motor? None of the cabin components have changed, just the engine.

 

well you see because from the shock tower (where the engine harness connects to) to the ecu will not have the 2 wires needed for vtec. and if youve ever taken a car/cabin harness out you would see that it is all integrated into one piece. so you would have to remove/ replace the whole thing...

 

just run wires from the VTEC solenoid and Pressure switch to the ECU

 

thanks guys i appreciate it. i saw a harness for like 55 bucks including shipping. so i was like awesome i dont have to wire all that up but thanks for responding to the post

 

Vtec is A4 and Vtec pressure switch is D6. The black wire in the vtec pressure switch goes to ground.

and if you gotta swap pins a6 and a11 cuz the POA ecu has the o2 and egr swapped if your using that ecu

 

thanks i appreciate it. i got a ex ecu i dont remember the code i think it is pob i have poa too if anyone needs one i wnat to sell it for like $40. if anyone wants it send me the zip code city state and address and i will check on shipping for you

 

you got it backwards, poa is vtec, pob is not

 

poa is vtec you're correct.

to HondaPartsHero! I actually bought an IAB and Knock Sensor wiring harness from him and they worked out great. Made wiring a breeze ...

 

yeah i have both ecus though so i know what one is vtec because taht one looks like **** but the one im selling is in great condition so i can always look at it before i put it in the car
