Swapped out the automatic transmission for a manual and now i dont have any spark

I have a 1997 TJ and i just swapped in a AX15 transmission. I hooked up all the plugs that i could on the new tranny but there are a couple that there is nowhere to plug them in. When i turn my key on it wont turn over and when i jump the starter with a screwdriver i have no spark Any help would be greatly appreciated!

There is a round plug that was on the drivers side of the automatic transmission. This has a wire that tells the computer and starter relay that the trans is in neutral or park to let the starter run. You are going to have to ground it. You will also not have any backup lights as the reverse switch is in the same plug.

And if you have not changed the engine computer to one from a manual transmission you will have a check engine light as there is no torque converter and the computer will throw a code when it tries to lock it up.

The Nss connector wires are

CAVI CIRCUIT I FUNCTION
1 I L1 18VT/BK I BACK-UP LAMP SENSE
2 I T41 18DG/YL I PARK/NEUTRAL POSITION SWITCH SENSE
3 F20 18VT - ~ FUSED IGNITION SWITCH OUTPUT (RUN)

Okay I grounded the neutral position sensor wire, and it will turn over now but I still don't have any spark. Any ideas on that?
