Default TPS + 90-93 mspnp blues

I have a 1.8 swapped into my 92. It currently still uses the 1.6 TPS.
I'm about to install my MP62 with the Big Throttle Body. It is setup for the TPS from a 1.8.
To add to the confusion... I'm using a 90-92 MSPNP.

Can I use the 1.8 TPS with the 90-92 MSPNP?
What wiring changes must I make? (the 1.6 TPS is 3 wire the 1.8 is a 4 wire.) I have connectors for the 1.8 TPS

Other options?

By default, the '90-'93 MSPNP completely ignores the TPS. You can modify it to accept input from a variable TPS by following the directions here:

just use the big t-body and don't hook up the tps. It will run fine and with enough tuning you won't desire v-tps, like my car.

I you decide to do something else, can I buy the 1.8 TPS connector off you?
