I believe I know what they all are, but let's see what we have. 3 pictures, 3 items circled per picture. As far as I know everything is where it would be on a stock K5 but a PO put in a 350 w/ Holley.

**JIMs70GMC** · 06-10-2015, 07:23 AM

No one wants to try?

**62 Longbed** · 06-10-2015, 11:08 AM

Its funny that you posted this ... I have the same questions since previous owner changed carbs and threw away and discarded a lot of lines and connections on my 1984 ... Wanna find out as well ..

esbstuff · 06-10-2015, 11:34 AM

I'll try...

1) Transmission shift thingly

2) Electric Distributor plug

3) Smog Solenoid Plug

4) A/C Pump wiring

5) Another smog thing

6) Dual Tank wiring

7) Cruise Control

8) No idea

9) Cruise Control

This should help...

**JIMs70GMC** · 06-10-2015, 08:34 PM

I think 1 and 3 are for the distributor and q-jet. 7, 8 and 9 for cruise control. 5 is the lock-up for the torque converter. Not sure about 2 and 4 or what 6 (2 wire plug) is.

**JIMs70GMC** · 06-11-2015, 08:49 PM

Nobody?

bdiamond · 06-11-2015, 10:47 PM

I believe #2 is for the converter lockup and #4 is A/C wiring. I think #6 may be backup lights?

bdiamond · 06-11-2015, 10:51 PM

Is that a clutch master cylinder and reservoir bracket I see in the last picture? If so then I don't guess you'd have converter lockup connectors....

**JIMs70GMC** · 06-12-2015, 05:50 AM

It is, I just converted her to a 4spd. I have not purged the wiring yet.

beamn7 · 06-13-2015, 02:54 AM

I'll play..

#1= EGR solenoid plug
#2= Spark advance switch
#3= EST (electronic spark timing) connector
#4= underhood lamp option?
#5= TCC (torque converter clutch) vacuum switch
#6= pressure differential switch connector for combo valve?
#7&9= vacuum hose that feeds vacuum reservoir that is mounted on drivers side inner fender or cruise control
#8= TCC test port

Odd that it has a TCC vac switch cuz I see a clutch master cylinder. Was the manual swapped in?

Yep, I swapped in an SM465/NP205 combo. I need to clean up the wiring now. Is #6 for dual tanks?

**JIMs70GMC** · 06-13-2015, 09:15 PM

Looks like all but 4 and maybe 6 can go.

silverbear · 06-14-2015, 10:22 AM

I agree the #4 is for the Ac compressor.

K5's were a single tank only so I don't think that's what it's for....

Checked mine, #4 is A/C comp as silverbear said and #7 is cruise

**JIMs70GMC** · 06-14-2015, 10:18 PM

Thanks. I will trace out #6 and see where it goes.
