ripleydale Posted February 12, 2012 Posted February 12, 2012 I’m removing my automatic and replacing it with a standard, and I’ve removed my air conditioning, but want the heater and blower to function. I’m at the point of cleaning up my wiring and my notes and pictures weren’t the best. Hope you guys might know what some of this is and confirm my thoughts. My first is that cloth covered wire that goes to the starter (I believe on the R terminal). Not sure what exactly has gone on here. My thought is it would have gone up to the coil. In my hacked up wiring, it is connected to a pink wire that goes toward the firewall connector. Does anyone know what that pink wire is or goes to? Since I’m going to run an HEI, I don’t need the resistance wire for the coil and my plan is just to remove it back to that pink wire and leave the unconnected pink wire in the wire bundle. Does anyone understand what the relays in this picture do? The one on the left mounted on the old AC box so I could mount it to the firewall. It must have got pretty hot at one point as the plastic on the connector is melted. Just sort of wondering if they’re really necessary. Where does the connector draped over the brake master cylinder go? Quote
LS5 Posted February 12, 2012 Posted February 12, 2012 Hey Kelly, electrical....oh Joy..... Top picture.... those are the wires that go to the starter and blower motor.. on the harness where it looks like the thickest wiring wrap is, there is that L shaped eyelet..that bolts on and held into place on a bolt above and back of the starter its actually a tranny houseing bolt and holds up that wireing harness...Yes that dirty white cloth one goes to the coil and you can run a straight Red wire in the future from the Fuseblock to the HEI later.. the orange wire is for blower and the rest to the starter itself... Pic 2... that relay on the A/C houseing is the breaker for you heater A/C switch in the car if it is shot you will have no HIGH on A/C or heat...the inline fuse could be gone as well inside the tube holder you can see that is black up ontop of the firewall. the other relays are TCS related stuff on the engine and tranny part...TCS meaning Throttle Control Switch.. Pic 3 hmmmmmmm . those over the barkes will have to think on that one but will get back to you..most likely another relay let me check my super thick shop wireing diagramme..Gonna guess A/C compressor wireing harness plug in....But thats a guess. Darren... anyone else want to chime in here...??? Quote
ripleydale Posted February 12, 2012 Author Posted February 12, 2012 Thanks for your help Darren. Can't quite figure out why the resistance wire from the starter is connected back to the pink into the wiring harness. You mention the orange blower wire. What blower? The fan motor in my car is connected by a different path. I found the orange cutoff when I unwrapped the wire. Thanks for the info on the relay on the left. Sounds safest to leave intact. Not sure I need the TCS stuff, but not certain the best way to remove it either. Might be wise to leave it in place to unless I can understand it better. Still not sure about the last one, but I'm sure I'll find it. Quote
ripleydale Posted February 12, 2012 Author Posted February 12, 2012 Traced the 3rd one back to those TCS connections on the firewall (relay on the right. Also have a dead black wire from the T400 that goes back to that middle relay/connection block (not directly connected but I assume part of the kickdown from gas pedal). I need to figure out more about removing that whole setup. Quote

Here is what I meant to say Kelly as I was too brief..In the middle of the picture I have here #7 area smack dab in the middle that Orange wire is noted as the Blower motor wire and yes we are both right I wasnt full in my details..the Orange wire is as you found cut and wrapped up as a close off wire for on Non AC cars its used for the blower motor but on AC cars it is cut and burried because the AC blower motor is supplied from as you said another supply which is a purple wire. if you back track it it goes from the blower motor hidden under the fender area and that goes to that relay I mentioned on top of the AC housing and then switches color before that relay to orange and then goes maybe 6 inches to that black plastic inline fuse holder where it changes to black and goes back to the Firewall fuseblock.. sorry I should have been more defineing...

LS5 Posted February 13, 2012 Posted February 13, 2012 If I'm not mistaken that Pink wire backtracks through the fire wall and up the steering column and is part of the White and balck goofy jigsaw plugs that plug into the ignition switch.when turning the key forward in the run position it gives both the starter wire and the coil wire its positive feed it needs to start the car and the positive feed for the coil to run the engine and then sit dorment once the car is running in conjunction with the purple wire.. That Black ground wire with a metal eyelet on it pretty much goes on the firewall just as you can see in your picture there about 2inches away and is held in place with a larger thread metal screw and is the grounding source for the AC relay and stuff in that area.Those 3 wires on that plug by the booster dont go to the compressor as I was guessing they should run over the firewall and plug into a Resistor plug point by the heater hose blower motor area or to the left of that relay in your picture..

ripleydale Posted February 13, 2012 Author Posted February 13, 2012 Thanks again Darren. I pulled the TCS out completely so we'll see how well that goes. It's sure going to look a lot cleaner. My connecter into the high fan switch is melted and cracked and I'm going to have to replace that somehow to make those contacts. It would be nice to eliminate that too. Quote
