can i splice the wires off the M/T speed sensor into the A/T lower harness? if so, what colors? I'm about to do my swap tomorrow, and realized i dont have a manual lower harness, but the snesors are all there with enough tail to be able to solder into my A/T harness.... or are the plugs even different? perhaps i'm overthinking this issue...

The harnesses are very different because the A/T has far more sensors and solenoids VS the M/T.

I am not sure how possible this is myself but check out the service manual for more help: http://Nicolub.com/FSM

Yes, I?m aware the harnesses are very different, but the only part I'm concerned with right now is basic functionality, ie: speedometer and reverse lights. I've read every 5spd swap walkthrough and build thread I can find on here, but can't remember seeing mention of this particular question/issue. I have a vert, and know about the mods needed for my top to still function and my car to start. If anyone has any input on this it will be greatly appriceated.

Oh, and if I do figure it out, I'll be sure to share the info here
