hey you guys i've swapped in a b20vtec into my 96hatch n i get a check engine light for code 21 vtec solenoid! do i still gotta wire up the solenoid,pressure switch, and a ground? even though im using a 98ex because ex comes w/ vtec already? any info would be greatly aprreciated!

try it with a new solenoid and check all the wiring.

 

what wiring would i have to check?

 

Did you wire in vtec? Haha..it just is funny to me! There are three wires for it i believe!

Thats what i was thinkin, and yes one for solenoid, one for pressure switch, and another for ground i dont know what pins offhand

 

wire up your solenoid, pressure switch, knock sensor and your ground.

How do i get this to go away....is there any wiring i was suppose to do prier to installing a vtec head on a b20? any info would be greatly aprreciated!</TD></TR></TABLE> check the voltage with a meter on your soleniod maybe its busted.

Are you serious? Did you think you could just put it on and it would magically activate on its lonesome - like some little gnome was going to pop out of the solenoid with a golden hammer and start banging more horsepower into your engine?

Yes you have to wire it up! Who knows how to do this mechanically but lacks the foresight to research it?

 

wow i toatally missed that he was asking if he neede to wire anything up for it to work LMAO

 

Yes, you need 3 additional wires for the two vtec components, a 4th if using a stock p30 or p72 ecu with knock sensor board.

Otherwise check the ground you used for the wire - mine was half-assed, and didn't work till I exteneded it to the battery, and later (cleanly) to the thermostat housing ground.

Hope that helps...

Kinda hard to resist being a smart *** when you slap a Vtec head on and expect the Vtec fairy to come out at 5200 rpm and begin unleashing the mAd TytE VeTEcH poWA!

Hope that Helps...if you need more help...SEARCH...I typed Vtec Wiring and got alot of stuff!

Good God Jesus Christ!!!!!!

YOU MUST WIRE UP VTEC!

Your chassis is a DX! DX DID NOT COME WITH VTEC!!

Even if you use a EX wiring harness, you still have to wire it up!

The only hatches that came wired up for VTEC is all 92 hatches and all Si model hatches.

If you want help, then don't be a f*cking jackass. Jackass!

hmmmm, i cant front i was thinking the same thing. I thought the purpose of getting a ex, si, gsr harness was so it was all plug and play and that you didnt have to add any wires to it.
Im doing a b20vtec with a p72 head and p28 ecu into a 94 EH. i thought that if i got the gsr wiring harness that it was all plug and play??

 

You still need to run wires from the shock tower to the ecu! Or if you're using a dx.vx..blah blah blah..you have to make a complete harness!

Research people!

 

aight thanks you guys i got it now...haha
