the heater core unit, blower motor unit, and logicon switch are from a 89.
i need to put this in a 87.
i know everything bolts in the same, but is the electrical the same?
are the locations of the terminals in the connectors the same?

thanks

 

Logicon has the same pin out as does the air mix motor and air mode motor, but the A/C is different. Don't know about the blower

 

thanks for the info icemark.
the blower motor should also work if im reading both diagrams correctly. the s4 has one less pin in the connector, but the locations and the colors of the wires are the same.

 

The blower motor has a 2 spade connector. I believe blue/white wire (power) and a black one (ground).

 

I notice that the S4 blower have a Blower Resistor contrary to the S5 blower that dont have one. I have a 87 turbo rx7 and I brought a S5 Logicon and S5 blower/housing assembly this combination will works into my 87 Turbo?
