wire harness info needed?!?!

[B20Civic92]

im doing the b20 vtec build and all i need to do now is install the wire harness, i have a b16 head and b16 harness, but when i looked to take the other one out, i noticed the it runs from the ecu and half of the wires go through the fire wall and the other half goes under the dash so i was wondering exactly what do i do about it??
any help would appriciated :boobies:

what kind of car and what year.....and that obd code r u swapping to?

[B20Civic92]

92 civic hatchback and it had b20 in it first (p75) so im guessin it was obd1 and its got a b16a head (pr3-3) so obd1 (i think?)

[hondalover00]

is this ray? if so text me and ill come and take a look for you and see whats up

[PURP]

If the harness for the B16 is obd1 then it should be plug and play. Now... your car being a 92, it is already prewired for vtec from honda. All 92 models were done this way.

But like I said, if everything from the main engine harness to your ECU harness is obd1, it is supposed to just plug right in. 2 plugs on the driver side. 1 big and 1 small 2 wire for ignition. Passenger side should have 3 with a 4th that is a dead end for the grounds(yellow wires).

hope that helps

No this is not Ray lol but yeah that's what I thought about the just plug and play but it's nothing like that at all lol I feel like I have to rewire the whole car and I kno I shouldn't have to

[punkr6]

has the car ever been swapped before ?

[B20Civic92]

yeah it has, i bought it with a b20 in it

does you harness go all the way to the ecu with no plugs inbetween the motor and ecu if so you have a obd2 harness not a obd1 cause a obd1 have plugs on the motor harness that plug on the strut towars on each side does go all the way to the computer as a complete on piece harness
