Probably easier to just ask RyWire, but yeah they take both harnesses, and turn it into a plug and play harness for the Type R motor.

Basically they put the connectors from the Type R motor on your Si harness then do all the wire swapping for the OBD1 ECU. So yes, they need both harnesses.

EDIT: Also you linked the wrong one. Here's the one you actually need: http://rywire.com/store/8891-c...91f30

 

ok thanks man just wanted to make sure.

 

so i purchased this........... Got my wires back and I had just putted them on my itr. Theres extra plugs and harness. can any body tell me what there for.


these ones look like there from my original crx si engine but some how still on with the new complete harness.


and this one

 

the first picture is your reverse light switch plugs.
second on should be your map/tps sensor. ( give me description on wire colors )

what tranny are you runnin? is the itr motor legit?

Actually those first plugs look like the ones to the master cylinder. Someone correct me if I'm wrong.

thats what i was thinkin too!

 

put it on your motor, if its closer to themaster cylinder, then its for that, if its closer to the tranny, then its for that...

Those are for the reverse light switch.

The master cylinder wires aren't a part of the engine harness. They are part of the actual harness that runs along the firewall under your carpet and to your ecu

Also the 3 wire plug your holding is for the tps sensor on the back of the throttle body. It couldn't be for the map sensor becuzz the map sensor plug is not on the engine harness either!

the first pic has nothing to plug onto the tranny. those are the left over plugs.. my type r , i don;t even think it has those original equip with those.

And yes there were no harnesses for the manifold at all. also, my original crx already has a harness for the map thats not on the engine harness. and i guess they added one on.

 

i found some pix for the itr revese switch plugs and IDK how those two plugs are suppose to fit onto mine. so now on my itr the reverse switch just hanging there with no other harnesses.

the colors are
red with blue strip,
yellow,
green with white stripe

 

any help...........

does anybody know if i can start my car with out the reverse switch? if not how do i wire them up.

 

You can start your car without alot of things, luckily the reverse light has nothing to do with starting your car. There should be a needle looking thing on your tranny for that to go on if its the reverse lights. it should be right under the distributor, i think.

 

Actually same thing happened to me. Havent figured it out yet since am not home but I think hydro and cable trannies have different plugs. They gave us the cable connectors which do not match the hydro plug. But you should be able to start your car without them...i did

yeah i thought so. but like you say if you can start it up without it.

 

Last ? what are the chances of me getting a cel check because my ecu does not have a light to check.

If you ground pin D4 at the ecu the check engine light in the cluster will blink just like the red light would giving you your codes

 

maybe i missed it if answered but maybe the plug is for the head? a temp dealy? my cel was on after i put my head back on and it was cuz i didnt clip that to a clip on my head under my dizzy

 

type r swap thats crazy hahaha nice man .

I have a B16B in my CRX, when I got the engine harness back from Rywire, they had used the CRX engine harness plugs (the one male connector and one female). It was a simple fix, just cut the plug from the reverse harness on the transmission and put the correct plugs to connect to the Rywire engine harness.

but the 2 wires from tranny are the same colors.
both wires are green with black and purple strips.
and then the complete harness has 2 wires.
a yellow wire And a green wire withe 2 black strips

 

should i just connect them to what ever wire?

 

It shouldn't matter what wire on the engine harness connects to which wire on the trans. The switch in the transmission should just connect the two wires together when in reverse.
