Lol Someone check my efan wiring diagram plz
So I decided to throw my LS1 fans in my old K5 Blazer and basing it off the original LS1 diagram I added a 3 position toggle switch to switch between a auto temp sensor mode (in series) to a full speed mode(parallel).
Add some breakers between the battery and relays maybe?
Original diagram I found:

Not sure what the blue box labeled "HIGH" represents.
Some problems with the diagram.
1.) Pink wire going to the switch will short out the system
2.) If you flip the switch on high only the left fan will come on high.
3.) If switch is on high, the temp switch losses purpose.
3.) Will have to have switch on low/auto in order for temp switch to work.
If you want to use this diagram I would recommend using two SPST switches and remove the temp switch from the series. Maybe wire in some leds so you know the fans are working.

Very CONFUSING.... and the coils of your relays do not have a ground.. im guessing that the off is the NC of the switch and a ground is there.... and also yes remove that pink wire going to switch, thats a direct short... ... whats the high box????
so when the low/auto is on it pulls in relay 1 and the fans are in series.. and when the high is on it pulls in relay 2 and 3 and 1 drops out so only the fan on the left works.. looking at the schematic that your are basing it off of the pcm pulls in relay one when its in low and then all three have to be pulled in to run in high! i dont see your setup working....

Nice I like those. Ill save em
I bought a dual fan harness from jegs the other night with a temp sensor
Ill probably wire in a switch and what not, maybe add another relay for low operation later on.
