I really need help with the 555H Immobilizer Bypass Module installation. The Car is a 2000 Honda Accord 6 Cyl. A DEI Viper 300 ESP was previously installed. I added the DEI 551T Valet Remote Start. The remote start works with the key in the ignition on the pre-installation test.

I have the 555H hooked up as follows:
Blue/White from Module to Blue/white from Ignition.
Black from Module to Ground.
Blue from Module to WHITE/ Blue at the H1 harness of the 300ESP Module.
Red from Module to Heavy Gauge White wire going to Ignition Switch.

I cut the Red wire coming from ignition.
Yellow from Module to Red ECM side.
BLACK / YELLOW from Module to Red Ignition side.
BLACK/ White from Module to Blue

When trying to program the Immobilizer I get the light when starting with the key in the ignition. It goes out just prior to starter kick in. showing that it learned.
I then try to start with the key removed and i don't get the start. I get one quick flash of the LED just prior to starter kick in. The Immobilizer light on the dash continues to flash indicating wrong or no caode. I have tried both of my primary keys and the valet key. I get the same result with all keys. I'm REALLY stumped.

No help profuse007. I do have a Service Manual as stated above. The wire colors do match the installation instructions. The manual does state that the 555H is for Honda Accord 1999 to 2002, mine is a 2000 so I don't think that it is the wrong module. I have tried manually grounding both the Blue/white(key sensing) and the Blue (remote start Input) both together and one at a time with the other connected as instructions call for. I appreciate the input and I'm pretty sure it's got to be just one small mistake somewhere. By the way I have soldered all connections as suggested in the installation instructions. I guess it could just be a bad module but I think that that's even a more remote possibility.

I do appreciate ALL input.

I have the 555H hooked up as follows:
Blue/White from Module to Blue/white from Ignition.
"Blue/white from Ignition" - you mean the key sense wire, correct?

Black from Module to Ground. --- good

Blue from Module to WHITE/ Blue at the H1 harness of the 300ESP Module.
The blue from module needs to go to the thin blue ground when running wire from the 551T, it doesn't get connected to the alarm.

Red from Module to Heavy Gauge White wire going to Ignition Switch. --- good

I cut the Red wire coming from ignition.
Yellow from Module to Red ECM side.
BLACK / YELLOW from Module to Red Ignition side.
BLACK/ White from Module to Blue
--- all seem correct

OK, Thanks for all of the help. Here is what I did:

I rewired the blue as JWorm said. I then tried all 3 keys one at a time and still NO JOY. So I thought just for the hell of it, maybe I can increase the transponder output from the keys by placing all 3 together, one in the ignition and on on either side of that. SUCCESS, It learned and is now working great.

Again, THANKS for all the help
