I installed a 3 channel moser 12 bolt and was wondering if theres a new harness I have to buy in order for abs to work or can i just use the old harness and plug one of the two connectors to the top of the center section?

 

You reuse the exiting harness. Bob

 

Awesome thanks for the help bob

 

Hey bob, does it matter which side I use? Plugged it in and still have the abs inop light on

 

I misread this when I told you that you reuse your harness. I initially thought you were just wanting to reconnect your 3 channel harness up to a Moser 12 bolt with ABS. I just now caught the title "4 channel to 3 channel" I take it your car is/was a 4 channel, and you're attempting to convert it to a 3 channel? If so, I'm not sure what you can do as if I recall they use a different ECU. Bob

 

yup car was 4 channel but the 12 bolt i got was 3 channel. so i guess im **** out of luck ha oh well as long as the brakes still work right?

thanks for the help, Mike

 

Yes, the brakes will still work just fine. You won't have ABS up front or in the rear, which is the way I prefer them anyway. If you slam hard on the brakes you'll lock them up, so you'll have to use threshold braking. Bob

 

You could get 4 channel axles and backing plates like your stock setup. That is the easiest approach. Actually converting to 3 channel is possible but a much more involved process.

 

Don't u need to change the abs block out??? I just pulled mine, it has 1 less brake line than 4 channel. Let me know if u need the abs block for 3 channel.

 

You can attack this problem that way but it's only 1 small part of the puzzle. There is a lot more too it than swapping the module.

Something else to consider is that the 3 channel rear will need 4 channel brake lines to hook up to the existing system.

 

Sounds like too much work lol and ya I used the same brake setup from the 4 channel.

 

Then get you some 4 channel Moser axles and you are in business.
