I answered a PM about this from the owner, but I'll put it here too.

It sounds like you are having a problem with hooking up the manifold valve. There is a sticky covering this....

I wouldn't try to swap the whole harness out of another R/T unless you have the R/T harness already along with the R/T computer. If you are going to use the non R/T computer, follow the directions in the link.

Let me know if that helps you

i seen that a few times.it has the r/t ecm in the car but the engine harness plugs are on the back of the engine an the engine bay harness plugs are down by the ecm.its not hard to change the harness again if i get the r/t one but if i get the r/t engine bay harness will everything work right.the engine bay harness really dont reach an if i make it then the air box hits it an its really tight I'm kinda tryin to idiot prof/make it a normal r/t as possible if i start putting relays an stuff an he has a problem later on down the road an takes it to someone else they might not know whats going on an why its set up this way an try an fix stuff that dont need to be done know what I'm sayin. i have run into that alot with honda swaps sorry if im being a pain if the car ends up with any codes i cant get out cause things aren't hooked up right the car wont pass an cant tag it

Here is some more info for ya from a PM.

The manifold valve actuator hook-up can be done with your exsiting harness and fuse-box. The only difference in the PCM (wiring-wise) is the added actuator circuit.

Are you using a factory service manual? That would show you what pin-out is for the manifold valve. It would be a matter of adding that circuit to your harness to create the factory circuit. Here is the pin-out for that connector.

ok so can anyone tell me if i put the r/t harness in will everything work ok or what?why wire things up if you can do it right the first time

r0nr0n · Post by **r0nr0n** » Mon Aug 04, 2008 11:23 am

the engine harness plugs are to the back of the engine an the fuse box harness plugs are in front down by the pcm this is why im asking about changing it i didnt wanna try an stretch them that far adding the wires for the actuator not a problem just the length on the whole thing has me stumped

Post by **occasional demons** » Mon Aug 04, 2008 12:29 pm

Either something isn't routed right or you're missing a piece of the harness, because the body and engine connectors should both meet at the PCM. Unless I am misunderstanding what you're saying...

Danteneon · Post by **Danteneon** » Mon Aug 04, 2008 12:54 pm

I'm confused as well. Both the 2.0 and the Magnum harness are routed the same as far as PCM and block sensors. The harness should reach all components unless you have the harness routed incorrectly.

na the engine harness is right where it was when it came with the engine it seem kinda funny to me that the plugs are by the back of the head everything is plugged in the way its supposed to be maybe whoever had it before ran it different ima go check it again but it looked right the first time i looked

the harness plugs im talking about are the 2 14 pin gray an black plugs sorry

r0nr0n · Post by **r0nr0n** » Mon Aug 04, 2008 4:50 pm

i checked it out the engine harness is right but the pcm plug an the 2 14 pin gray an black plugs are real far apart not like the one that was in it the old one had all 3 coming out the harness right near each other by the pcm the pcm is pluiged in but the others well they just dont reach i took pics but i gotta email them

Danteneon · Post by **Danteneon** » Mon Aug 04, 2008 4:58 pm

Hmmm. Yeah, some pics would help a lot.

this is the old harness see how all the plugs are right there[img][img]http://i45.photobucket.com/albums/f86/s ... 0_0196.jpg[/img][/img]

now on the car the gary an black are to the back of the engine an the on to the pcm is running down by my hand [img][img]http://i45.photobucket.com/albums/f86/s ... 0_0194.jpg[/img][/img]

Based on what I see there, it looks like the engine side of the harness is coming up over the water lines. I think thats the problem. I will look at mine tonight to see how they should be run.

Also, is the plug you have from the PCM the original non R/T harness?

r0nr0n · Post by **r0nr0n** » Mon Aug 04, 2008 8:17 pm

yeah.. thats what im sayin i need the r/t engine bay harness its to short to reach the engine one its over the water lines so i could get it closer if i go under they dont come close at all

i got everything r/t except that 1 harness

Danteneon · Post by **Danteneon** » Mon Aug 04, 2008 9:02 pm

I would suggest getting that harness. It will make your life a lot easier.

r0nr0n · Post by **r0nr0n** » Mon Aug 04, 2008 9:35 pm

lol is your harness longer where they split from the pcm to the engine?an if i change it the mtv should be good also right?

I cant find that harness anywhere... had a few leads but they left me waiting.. so its been like 7 weeks.. is there anything esle that can be done.. my car hasnt ran in months

Danteneon · Post by **Danteneon** » Tue Sep 30, 2008 3:19 pm

OK, I have some more info for you.

The connectors you have in this photo...

They shouldn't be going toward the front of the car. They should be run in this area...

So that leads me to ask...did you remove your 2000 harness at some point? The two connectors that are in the bottom of the first picture shouldn't be up front at all, but mounted to a bracket that attaches to the firewall behind the battery.

I suspect that while the engine harness is oriented correctly, the body portion is not. Can you get some pictures of the body harness, particular where the under hood fuse box is?
