I put a hicas lock bar in my 34gtt series 2, unplugged all the plugs hooked to the hicas motor, tied them to the lock bar.
I dont remember exactly if i hooked anything back up and have had no problems with ABS or traction for over a year now
heres a pic of mine just 2 compare, it looks as tho the blue one is the one that needs to be plugged back in
