Greddy Speed Limiter Cut Question

[honestabe]

Ya'll know I got an '87 1J. Question is, what wires on my Greddy Speed Limiter Cut device go to what? I have 5 wires: Blue, Yellow, Red, Black, Brown. Pics would be most helpful. Thanks guys. Hitting 108 MPH sucks.

1. your speedo is off, speed cut is 112mph (180 kmph)
2. you dont need a greddy speed cut defencer to go past 112, just cut the pink wire going into the ecu. doing this has no negative side effects (including engine light)

My speed cut is checked by GPS, which is 100% accurate as tested by 2 police radars. Also, you have to take into consideration different tire size and tread wear. I don't want to cut the pink wire because that will give me a check engine light and I don't want that. since it will drive me nuts. I don't like warning lights to be on for no reason. The SCD is the propper way to go above 112 MH

It will throw a CEL over your speed cut, not all the time. It is nice in that face, because it tells you to slow the fuck down

So long as the CEL only comes on above the speed cut I'm happy.

Indeed, I have had this for a year or so, CEL only comes on over speed cut.

Ok, so what wire goes to what?

Nope, nothing to do with idle speed, I idle just fine
