ok so i swapped a 99 b20 jdm into my 97 civic ex

the tach doesnt work and i was wondering where i can find the wire that sends this info to the guage.

i had to change the dizzy plug from obd2b to obd2a, and the blue wire(9) is just sittin there not hooked to anything

what do you mean its not hook? you mean theres no blue wire on the dizzy? or theres no wire on your harness?

 

only two things make it not work, the signal wire from the dizzy or the guage cluster

 

i have the wire from the harness but the dizzy doesnt have one

 

I recently learned that 99-00 Civics get the tach signal through a blue wire from the ECU rather than from the ICM in the distributor. This could be the problem.

 

what do i have to do to get my guage to work again?

 

That's the $64,000 question. Not sure what ECU or wire harnesses that you are using. For 99-00 Civics, the tach signal comes from the ECU on a blue wire through connector C442:

 

im using my auto 97 ex harness

 

You need an ICM with a blue tach wire or a 99-00 ECU with a blue tach wire.

 

i just bought a 96-01 b18b dizzy

 

im having a similar problem my fuel needle aint moving?

 

Here's a question for you guys:

I have a 2000 Honda Civic DX/Auto (Bone Stock)

The stock cluster doesn't have a tach, can I swap my cluster for a 00 Civic EX/LX/Auto and will the tach work automatically; or will I have to do some hardwiring? Thanks!

 

So if I have a 99 civic and I am using the obd2b -obd1 harness and a PO6 I will need a 96-01 b16 distributor and tap the blue engine speed wire to the body harness tach wire? Does anyone know which wire is currently running to my tach?

 

manual and automatic clusters are interchangeable.

 

Nevermind it works!!!

Okay thought id explain this since I finally figured it out. Heres my setup:

1999 civic 4dr, d16y8, 5 speed
OBD2B - OBD1 conversion harness
Neptune software

MY INSTRUCTIONS

If you take the distributor cap, rotor and cover off you will see a spare male terminal on the ignitor (next to the rotor shaft), simply run a wire from that spare terminal to the blue deadend plug with the black weather cover over it on the driverside strut tower by the hood prop and BAM!! The tach will work.

 

^^^^^^^thank you ^^^^^^^

 

You can plug in a 96-2000 LX or EX cluster straight in. CR-V clusters will too. You can either use a auto with the gear indicators or a manual. The Auto clusters are in less demand so are generally less expensive. Browse the marketplace forums. You can get them on ebay but don't pay too much for one, especially an auto cluster.

 

My car stalls once i connect that wire to the shock tower plug. Then i got code 14

1999 honda civic Ex obd2b
Auto chassis
Chipped/VTEC P06 obd1
Manual conversion
Obd2b to obd1 harness

 

Bump. I really need the help im going crazy

 

Than don't connect it to the shock tower??!!??

 

If u actually read everyone elses posts u would know thats what ur suppose to do. But when i do it it ***** up n shuts off my car, unless i cut the a19 wire then the tach shoots up past 8000 rpm
