When cutting speed limiter.
pink=Speed 1 output.(THE SPEED WIRE HAS TO BE CUT)(the pink wire joins to the wire from the ecu side)
purple=Speed 1 input(the purple joins to the wire from the loom side)
NOW FOR THE PIN OUT
IG power=22P /bottom row first on the right /plug 4 (as in its the first plug on the right)
RPM=28p /bottom row 3rd from the left/plug 3
GROUND=24p /bottom row first on right/plug2
SPEED=28p /2nd row down first on the left/plug3
(22p/28p/24/thay stand for 22/28 and 24 pins as in the number of wires comeing out of the plug)
hope this helps mate.its the best way i can explan it.
