    71 GTX Air Grabber Switch wiring schematic

    Wiring? The solenoid lead? One green wire with a bullet connector, connects to the yellow tree-way accessory tap in the dash harness near the radio. As shown, all other "connections" are vacuum lines.

    Reverse lamp wiring for a 4 speed 1971 Road runner

    I agree, have done the same thing myself several times, there is no technical need to make this indicator light connection in the engine compartment. That’s just how the cars were assembled originally. I certainly wouldn’t be drilling any new unnecessary holes in a freshly painted firewall for...

    Reverse lamp wiring for a 4 speed 1971 Road runner

    In ’71? Hole in the firewall? Just for the dash mounted reverse indicator light’s wire and gromet. Connects to the pigtail in the above diagram on the engine compartment side of the firewall. Bee71's pic above shows the reverse indicator light wire grommet location.

    1971 Charger unidentified hole

    Yea, you are correct, just went out and verified the switch is further outboard, up on that step. Your pictured holes I don't believe are original.

    Vapor lock 6-pack question/solution

    Not correct, perhaps you should have a looked at the factory service manuals from ’70-71, relating to the Evaporation Control System, it's function and the correct information on the fuel bowl vent valve hose routing. Called Holley? Did you ask them why the current re-issues of the ’71 center...

    Voltage over 15 volts at all times. Stumped, see diagnostic list.

    Could have missed? I pointed out in post #33, you would be looking for a high resistance connection causing your 1.3 volt voltage drop between the battery post and the voltage regular reference based on information you provided in your first post. Also described how you could isolate the exact...

    Voltage over 15 volts at all times. Stumped, see diagnostic list.

    There is nothing uniquely mysterious about the 12-volt electrical systems in these cars if you know what you’re doing. I’ve been wrenching on these cars, and others, professionally, and otherwise, since my time at Chrysler dealers back in seventies. Pretty sure that qualifies myself as one of...

    Voltage over 15 volts at all times. Stumped, see diagnostic list.

    If you are referring to the undercurrent-rated Packard terminals in the charge circuit at the bulkhead connector, that’s a well-known Chrysler weakness that dates back to when these cars were relatively new. Plenty of other threads on that subject here. As for “Mopars are notorious for over...

    Wire Harness for engine, neutral safety switch, and front lighting for '73 Dodge B body

    If you already have a usable blower motor and A/C clutch harness, just remove the male Packard’s from the old bulkhead connector and transfer them to the new one connector in the same position. The A/C related harnesses were meant as add-ons to any other harnesses, not going to find repos of...

    72 Charger Steering column modification

    A potential safety issue to run it without the spring. Should the collar move or remain in the key release position, there is the potential for the wheel to lock if the ignition is switched off while the car is in motion. The original spring is uniquely shaped, a substitute for it would not be...

    Voltage over 15 volts at all times. Stumped, see diagnostic list.

    Not seeing any posts addressing the voltage drop noted in the original post. You have a 1.3 volt voltage drop between the reference voltage lead at the regulator (blue wire) and the battery while under load? That needs to be corrected, take voltage drop measurements at all the connections...

    1970 Dodge Charger 440 4bll carburetor questions

    Nothing to disagree with in the first sentence of that post about low performance 440 OE Holley’s, including the reference to low quality, didn't see a reason to quote it. Only taking issue with the comment about 440 HPs never having run Holley OE carbs, no specific to model year range...

    1971 road runner Carburetor & Distributor Woes - Please Advise!

    The OP specified a manual transmission, had it been coded for N96, R-6193A would be the correct original list number. List number R-4735A is N96 automatic transmission only.

    New (yes....) fuel tank, cap won't twist into place? 72 Satellite wagon...

    Except Station Wagons, the fuel cap/filler tube change took place March 1, 1972, it was a mid-year ‘72 change.
