I got a really good deal on this car due to the issues with the wiring, so I am hoping I can get some help from you guys. A little background on the car.............the car was built and cranked before on a Chasebays harness, but there was an issue in the harness for the Map sensor. The harness was taken off and replaced with a Rywire mil-spec harness for an EK with an OBD-1 ecu plus Rywire EK subharness.

The car is a 1999 Civic Si with a turbo-charged d16z6 making 550whp. Car has a p28 with a hondata s300.

I have a concern as you can see the Chasebays sub-harness for an EM1 is much different than the Rywire harness for an EM1:

Rywire on the left and Chasebays on the right:


With the chasebays harness on, the car cranked, windows rolled up, everything worked fien except for the map sensor. Now, with the Rywire harness, when the car is on, the windshield wipers come on and will not go off (the wiper switch on the sterring wheel is off), and the windows will not roll up. All I am lacking is this freaking harness to get the car running so I can get to the dyno and then the track. Below are some pics of the wiring....and if I can take any other pics to help you guys, that would be no issue.









Thanks,

Ryan

 

I'm confused is it also a dash harness?

 

Silly question, but have you contacted Rywire?

 

yes, it is for the dash and engine.

 

rywire doesn't open until noon (my time) and I'll be at work then, so I was hoping to get some help from the forum first.

 

Is the Chasebays harness a different OBD?

 

Same OBD, they just make their's different.

 

Im not sure how its setup but Can you use the Chasebays harness and wire the map sensor straight to the ecu?

 

For future reference the wires that need to be tapped into the A plug need to be tapped into the original a plug from your car that is attached to the interior harness, not the A plug on the Rywire harness. I am glad I could help Ryan let me know if you have any other questions.

David,

We ran into a few more issues, but I'm pretty sure its a simple fix. Ill call you today.

this.. i had the same issues with my em1 with a rywire harness. some of the colors won't match up directly. you'll have to find what each one is. orange and the white w/ black stripe are extra wires..
