It's not too late to sign up and meet us all in Carlisle, Pa in a couple months either. So far, it's the largest gathering to date, with something like 80 members, and well over a hundred with family members included. Great way to meet a lot of really fantastic people, and also share the trip with your family too, if wanted.

I use the CD's a lot when researching stuff for the forum, plus it's easier to screenshot, or save as .pdf files to share. In the shop when looking for torque values or capacities, etc, thumbing thru the paper manuals is usually quicker for me.

Real nice looking car Cory, good for you! We're here to help, plenty of knowledgeable people here. Don't hesitate to ask. Joe T

I found this, BUT....while looking thru their OEM harness catalog, it says that 1970 doesn't use one, it's part of the engine harness. Below is for 1971-72. https://americanautowire.com/products/transmission-kickdown-harness-ca11896 Catalog below, go down to page 51 (of catalog itself, not the .pdf legend page number - Chevelle, Monte, ElCamino section), look under trans kickdown harness. https://api.americanautowire.com/shopify/catalogs/2020_FF_Catalog_Combined.pdf I'm going to PM you my phone number, It'll be easier & quicker to help you.

I just had one in my hands the other day, while looking into Dave's problem. It's about 8 inches long, with a grommet to go thru the firewall. This is the one that came off my car. If you think that's what you need, I'm pretty sure American Autowire or M&H will have it. Confirm it's the one you need & I'll poke around and find you a part number.

Are you looking for the wire that goes from the pedal switch to the engine compartment harness, or something else?

Look at pages 748-750 in the 70 assembly manual, also called M40, sheet A6.

To me, all 3 are essential. GM Service Manual, Assembly Manual, and Fisher Body Manual. The GM overhaul manual comes in handy sometimes, but focus more on specific parts such as the transmission, rear diff, power steering pump/gear, etc. It's a deep dive in the repair/overhaul of major parts. You can buy a CD with all 4 manuals on it for around $35 from a couple different sources. I tend to like the paper manuals though, so I have those on hand for the year cars I own, as well as the CD's.

NAPA too

Call Denny's driveshafts. They'll have solutions/answers to all of your concerns. Top notch workmanship too. https://www.dennysdriveshaft.com/index.html

I wonder if we can find the real owner of that internet pictured car, and maybe get him to be a club member...

After looking at my old harness, it appears that the power for that switch goes thru the Radio/TCS Solenoid 10 Amp fuse, thru the power bulkhead in the engine compartment, and then to a short pigtail harness that goes thru a hole in the firewall to the Accelerator switch. From there, it would go to the transmission mounted switch. Dave and I were on the phone a few times and were both using multimeters at the same time, on our perspective harnesses, figuring out the circuit, lol. He doesn't appear to have power coming thru the engine side wire, which could be as simple as a poor connection at the bulkhead mating halves, or as bad as a broken wire. He tried to move the bulkhead connection a bit, but its location, plus it being bolted together produced no favorable results. We decided, If later attempts to re-seat the bulkhead don't work, a short jumper from a switched fuse block stab will work to power up the circuit. None of the diagrams or manuals I have showed that accelerator pedal switch.

I can't find any diagrams or schematics that show the T-400 (M40) trans wiring either. One place suggested that the feed wire came from one of the 12V switched stabs on the fuse block and goes to one side of the accel. pedal switch. I can't verify that though. Maybe I'll go up in the attic and see what my old harness shows. Can you trace any wires from the switch connector back?

You can weld them with nickel rod, but you need to take steps to prevent cracking (preheat, etc).

I'm still looking into the side marker ones, so don't order anything just yet. The tail light numbers are good though. It says this number below is for the rear side markers, but I'm trying to confirm it with the assembly manual: https://www.amkproducts.com/search-result/?ser=g-4228 EDIT: For the front markers, your assembly manual will be page 12C-3, items 2 & 3. Those numbers look good for the G-4201 kit. I don't believe them in regards to the rear, I think just using the same type screws as the front markers will work fine (B-12152) So, I'd either order 2 of the G-4201 ($3.50 each), or get some bulk kits, with all the fasteners, and some left over. J-nuts (8 of them - $4): https://www.amkproducts.com/bulk-fasteners-products/?Product_ID=12245 Screws (12 of them - $4): https://www.amkproducts.com/search-result/?ser=B-12152 Realistically though, NAPA would have J-nuts that work, plus some #8 screws. Would be a lot cheaper once you figure in shipping.
