Need help wiring 3rd and 4th gear pressure switches

[dyermullet]

Once I got my replacement trans up in the car I dropped the pan and found this.

Their are no wires connected to the solenoids. I am going to pull out my factory manual tomorrow but I need some help. The trans is a 84-85 and my car is a 87. It looks like it has the two pressure switches that I need. I labeled them 1 and 2 in the picture can someone tell me which one is 3rd gear and which one is 4th?

I need to buy the connector for those switches, and I need the 4 pin connector that passes through the case.
Where can I get those, does anyone have part numbers or a source?

Thanks

4th p.s. is pointing at the ground, visually "near" your cat.

IIRC, your other is a temp switch. But don't quote me yet.

#1 = 4th Pr. Switch.
#2 = 3rd Pr. Switch.
Temp Switch is missing, if it even had one.
Looks like >> http://www.makcotransmissionparts.com/D74437.html normally mounted at rear of Vbody close to 3rd Pr. switch. Not all Trans came with them.

TCC Case connector:

Do you have the small 4-Pin connector that plugs into the back of this?

TCC Pigtail connector > http://www.repairconnector.com/products/GM-Transmission-Converter-Clutch-Pigtail-Connector.html

Eng. Temp Sensor & Pr. Switch Conn. 'Nail Head type' >> http://www.repairconnector.com/products/GM-Single-Wire-Coolant-Temperature-Sender-Connector.html (Probably available @ local Auto parts store in Help section).

May be able to grab a used Harness from a Trans Shop or Vendor on here & save some $$.

Is the 3rd gear P.S. found only on the BRF valve bodies ? Dumb question from a streetrodder but , I assume it does not lock the converter in 3rd gear ? Does it just tell the computer to do ??

I think it just lets the ECM know it's in 3rd by cutting the -Ground signal to retard ignition timing on the Turbo cars.
I haven't seen a 3rd gear switch on non-turbo cars.
