Need Info from 81 FSM

["DAVID MORRISON" <drmcross@xxxxxxx>]

Bill:

 

Thanks for your detailed response.  Really appreciate your help.

 

Yes, we are in the same row on bulkhead disconnect.  Your 81 FSM gave me a clue that this is somehow related to the throttle body relay.  I traced the #5 cavity black/gray wire in the engine compartment and it clearly goes to the throttle body switch relay.  My 82 wiring diagram shows this should be white/tan, which is what is connected to the stop light switch.

 

Here's the interesting part (maybe just interesting to me): there are TWO throttle body switch relays, side by side on driver side upper fender next to speed control servo.  My 82 EFI has just the one.  Both appear to be original, as does the wiring.  Does anyone else have this?  This car was originally California-titled, though can't think of any pollution-related reason for this.

 

To bring my story to a close, everything seems to be working fine, so maybe I should just keep my hands off what your compatriots wrought some 21 years ago.

The errors on page 8-178 are more due to my eyesight and not realizing Y
came before J.

So, ignore my previous email and do it right this time -

On page 8-178 the manual lists the bulkead connections :
#1 - Red - Speed Control
#5 - Light Blue with Yellow : Fast Idle Solenoid - non EFI
#11 - empty
#39 - empty

First of all, just to be sure, the #5 cavity is on the bottom row, which is
the row next to the large index.

On page 8-444, the manual list the bulkhead connections for engine
compartment circuits :
#1 - Dark Blue with Red - Speed Control
#5 - Black with Pink - Throttle Body Switch Relay (EFI only), or
       Light Blue with Yellow - Idle Stop Solenoid (non-EFI)
#11 - White with Tan - Stop Lamp Switch Relay (FI only)
#39 - Dark Green - In-Tank Pump Resistor (EFI only)

On page 8-445, the manual list the bulkhead connections for instrument panel
circuits :
#1 - Dark Blue with Red - Speed Control
#5 - Black with Pink - Stop Lamp Switch * (EFI only), or
       Light Blue with Yellow - Idle Stop Solenoid (non-EFI)
#11 - White with Tan - Hazard Flasher Switch (EFI only)
#39 - Dark Green - In-Tank Fuel Pump Fuse #2 (EFI only)
* Listed as #11 on pages 8-444 and 8-445.  The wiring diagram Y7 shows this
wire does go to the Throttle Body Switch Relay.

The 1981 manual does not show a Black with Grey wire connected to the
bulkhead disconnect.

Checking the wiring diagrams for the radio and power antenna, neither has
wiring through the bulkhead disconnect.  The radio wiring is all inside the
car, while the wiring for the antenna passes from the interior to the
antenna via a hole (with grommet) on the right side cowl near the floor pan.

But this still does not answer your question, though.
