I realized right away that 22g is too small for the coils and injectors.
Blue is from the ecu and green is 16g tefzel. The small red is 22g tefzel and the monster red is the cheap 18g I bought from a local race car store locally.
So I went back to reading manuals and what David told me plus his video on how to wire the MSD relay.
Switched 12 volts will be coming out of the relay with 20 amp protection. So when the on/off switch is turned on I’ll get 12 volts for things like the injectors, coils, etc.
For the coils I have a Spark Pro 4 and the manual states 20 amp max current. 14g is good for 5.5 ft of length so I’ll order 25 ft to have a bit of extra length.
Fuel injectors- the manual says 5 amps and David says he uses 18g from the relay. The stock wiring diagram has a 10 amp fuse so I used 10 amps in the calculator. I need 4 ft of wire for each injector and 18g is good for 4.3 ft @ 10 amps. I’m ordering 50 ft of that and will use it for the tether and on/off switch.
I like to draw stuff out still:
I think the socket marked o/w from the start/stop switch can be 22g because it’s just triggering the relay.
Thoughts? The math seems correct to me. All of the other wiring I’ll use 22 gauge except the fan. The green 16g is for the fan.
I’ll place a $200 order for this stuff soon hahaha
