What's different? The connectors or ? If memory serves, the only connectors are the encoder (shift motor), a switch on top that locks in the front axle, a syncro clutch connector at the rear, and a front & rear speed sensor. Could you swap those components to the newer t/c and plug in your existing wiring? I think they all unbolt or screw out except for the syncro clutch. You might have to change the connector on that.
Hope this helps,
