KA/SR swap Tranny sensor questions

[srJOEYdet]

I was installing my s13 180SX redtop Sr20det in the place of my old Ka24DE in a 91 240sx fastback. There are some tranny sensors I am confused about. I would post pics, but imagestation is down.

On my Ka24, there are five sensors, a speed sensor, and four others. On the Sr there was only three, a speed sensor, and two others. I know why though. My Ka has cruise control, and the Sr doesn't. I am assuming they both have sensors for reverse lights, and the clutch for starting the car. The Ka has two most likely involving cruise control I know nothing about. The only two sensors I really know how to hook up are the speed sensor and the one closest to it. They are both the farthest back on the tansmissions.

One last thing... when I switch the plugs on my SR tranny to the Ka plugs for my KA wiring, how do you know which wire is which? Or does it matter?

Thanks in advance,

Joey
