1991 4t60 TCC wiring

Just threw a '91 4t60 in my 86 LeSabre (literally 100% bolt on but this one part), but need the schematic for the TCC wiring 'cause I want a fully functional transmission. If anybody has one or knows off-hand that would be great.

The '86 has a 4-pin connector but only uses three pins. The '91 has a 5-pin connector...all I'm concerned about is that the TCC engages in third and fourth gears, though I would like to know what the other wires are for.

Okay...

Here is the stuff I needed, just thought it would be appropriate to share in case anybody else wanted to do what I did. This allows the TCC to engage in 3rd and 4th only as it is intended to.
