well the only thing left to do to get my b16a3 swapped ej8 is to wire it up, unfortunately i couldn't find any wiring diagrams for my specific swap (maybe i didn't look hard enough?) but my ej8 also got converted to a 5 speed in the process.

if anyone has any info on the wiring for a b16a3 into a 99 ej8 that would be really appreciated.

thanks.

 

What motor harness are you using?

 

using the del sol dohc vtec (1995) harness

and also, since it is a b16, does a 99 civic si motor harness work?

 

That may not work out too well. YOu have a 99 civic which is an OBD2b car, and all 1995 and below civics are OBD1. Thats a compatibility issues between motor, wiring and ECU's. Your best bet is to use any 99-00 civic SI wiring harness and ECU, and youd basically be set.

 

is it possible to use the automatic wiring harness that came on the d16y8 out of my car?

i already have the automatic to standard part of the wiring conversion done

 

use your ex harness...youre in for tons of trouble if you dont

practically everything will fit the a3 just as it did the y8 (proper ecu aside)

 

well i guess i have to splice plugs of the a3 harness into the stock y8 harness

i have read up on the wiring issues so i guess i know what to do...

 

get the proper distributor and a jumper harness and you wont have to rewire anything

 

ok ill take your word for that one, but the d16y8 was an AUTOMATIC and since the wiring harness was from an automatic, it will still work right?

cuz i know theres the automatic shift sensor kinda thing inside the car and i corrected that so it should be able to start...just my cluster will read that it is always in park

 

as long as yoube done the basics of the auto->5sp swap, its all the same connector

 

well what we did was cut the white plug with the yellow wires under the automatic shifter and spliced the 2 yellow wires together so my cluster reads that my car is always in park.

we also removed that little silver piston thing on the white plug so i can take my key out of the car when i turn it off.

is there any other basic stuff that i skipped as for the auto - 5 speed conversion?

 

wait, the wires arent yellow, theyre 2 black ones and one black and blue one and i connected them together

didnt want anyone to think i screwed up the wrong plug

 

also, since im going to using a obd2b to obd1 jumper harness, do i have to wire in the vtec pressure sensor since im running a p30 obd1 ecu?

 

unless your running some sort of vtec controller you need the pressure switch wire hooked up to the ECU..

 

yes i am aware of that.

just to clarify once more, my automatic wiring harness from the d16y8 (vtec) will work right?

 

ok, i have gotten my hands on a 99 civic ex wiring harness and i need to find out which plugs are for what....

so is there a site of a wiring harness with labels on what plugs go where?

thanks

ps: ive seen them before, just dont know where..

 

the reason you cant find any info is because it isnt needed. everything plugs back in the way it came out, if it doesnt seem to reach the right spot...it doesnt belong there.

 

well the dizzy, 4 injectors, and alternator plugs don't match up and since the engine is already in the engine bay, i dont want to take any chances (oh btw, NOT wiring up the engine before dropping it in was not my fault)

 

you'll also have to wire it up for a 2wire IACV as wheres the automatic has a 3 wire IACV, depin a14 to a12 and depin a13 and leave it unpinned at the ecu plugs if your planning on using your y8 auto harness. use the injectors from your y8 so you wont have to rewire the injectors.

 

well i should be getting a 99 5-speed ex harness in the mail today

i know that i don't have to do the iacv mod, i can use my old injectors, i have to splice the dizzy plug and the alternator plug.

am i correct?

 

and i am not sure if i have to splice the idle air temp sensor.
