Can you share which delay relay you used? I’m thinking I want to add the same to my electric fan setup.I recently charge my new vintage AC system in time for the scorching out PNW weather. Running AC around 90 degrees + tends to over heat my 40. I need to bounce back and forth between hot and cold. I don't have enough miles to find a happy mid point where I get some cold air but the water temp stays below 220. Even with a Ron Davis radiator?!?!?
Last time I was driving, it got super hot. Hit 240 when I arrived home and after shutting it off, heat soak drove it up to 245. Found that I melted my electric fan wire and the fan stopped working. The fan and horns were some of the worse wiring it did so it's time to clean it up.
I was running iRapsody relays off amazon rated 80/60, but there are a lot of comments saying they are closer to a 40/30 amp relay. I got invested in a Dakota Digital 75 amp relay, kept the iRapsody for the horns and bought a Hella, Delay off relay. Since I'm running a sniper, I have two fan switches and plan to run the first fan at 190 for the electric fan and 210 for the delay relay. The relay is set for round 150 seconds and if I turn the engine off when the temp is above 210, it'll keep the 75 amp fan relay on for a little over 3 mins....hopefully, no more heat soak.
Back to the new wiring. Replace the 14 gauge fan wire with 10 gauge, re-ran the horn wires and consolidate the grounds. Here is what I started with:
An long, laborious process, wrapping everything in Raychem DR25 and fixing the ends with Raychem SCL.. Here is the progress pick:
With wires going everywhere from relay to fan, relay to ground, relay to switches and relay to power, it was super difficult to route everything with our creating big bulges in the wiring loom. For a couple of the wires, I cut them and then inserted both ends into the same side of a barrel connector to get a clean 180 degree turn. Here is some more progress:
I first put everything together with the wire looms too long, and then cut them to size. I had to label each layer as it removed it so I knew the order to put it back together. I think I took the loom apart around 10 to 15 times to get the right sequence and layering.
Final product, it's no @Coolerman or @ToyotaMatt job, but it'll work under my hood:

Will be curious what it does to your coolant temps running the a/c.... I have recently installed a rebuilt 2F with a brand new 4-row radiator, 190deg thermostat, waterpump and direct drive fan (no fan clutch) and am having similar overheating issues when running the vintage a/c when outside temps top 90F both city and even highway driving.
(Have burped it numerous times with no additional bubbles after the initial burp)
Wise decision on going with the original carb. My brothers ‘76 had a Weber, found original, had it rebuilt and it runs excellent!Got back to it Saturday after stabbing in rebuilt 2F in July - un-Webered the past and got original carb on - had to get accelerator linkage (thx @65swb45) and choke cable and spring for carb (thx @ToyotaMatt) - installed fuel pump, water pump, clutch slave & master (txh @cruiseroutfit).
PO did a number to the accelerator pedal (hacked it off and welded the cable for Weber - so looking at local source for a pedal -
Manifold back from machine shop - and tightened a bolt or two and bent fuel line for the first time. Got it to turn over (wasn't getting gas to Carb) - Ended up an issue with the fuel pump spacer - Found a few small leaks - adjusted valves for first time - hell all this is first time for me (using friends garage and tools). Will put cleaned cover on when most of the fingerprint potential subsides.
Thinking of blasting and powder coating air cleaner and get that on-
Soon will turn drain the water from radiator (better than filling with $100 of antifreeze and find problems) and add antifreeze etc. Then to suspension and front axle (knuckles, brakes, hubs etc) then enjoy, before OCD kicks back in and I look for original seats - well shoot - (that didn't last long) need to start looking now.

I’m sorry @Skreddy , I really didn’t look at anything other than vintage air.@MaltbyPenn can you share any insights of why you chose Vintage Air over another brand like Classic, etc? If you compared at all.
