[burbanswervin]

im installing e-fans in my 1996 gmc suburban k1500 and i just wanted to know where i should wire the switched ignition. in the fuse box there is ign A and ign B do i wire to one of them?

Are you using the FSM ? What do your instructions say to wire it to? Does it say " ignition circuit" or " switched hot with ignition switch in on position?

these are the relays im using and the diagram that came with them. All it says is ignition. I know it needs to be a 12v switched ignition.

More correctly it a power source that's hot when the key is in the ON/RUN position. Not the ignition circuit.
Are you attempting something that your skill set, needs a more direct assistance ?

Considering the bad reputation e-fan conversions have gotten, I hope you find happiness.

If your objective is to improve engine cooling or AC performance, take heed.

The relay coil only draws milliamps so you can tap the to any wire that turns hot with the key on, just stay out of the ECM circuits. Like the fuel pump circuit.

MOST electric fan conversions create more problems than they solve, cost too much money, and just generally suck. Having spent a pile of money, folks then need to throw it all in the trash and buy a new fan and fan clutch, shroud, etc., because they have created unsolvable overheating problems.

It takes REAL engineering of electric fans to merely equal a decent fan/fan clutch system. The only genuine benefit to electric fans is that they can continue to run after the engine is shut off. Aside from that they're mostly a waste of time, money, effort, and enthusiasm. Electric fans were made popular by transverse wrong-wheel-drive applications where the accessory drive is 90 degrees to the side of the front-facing radiator.

Not worried about that at all, did the research bought all the correct parts custom radiator with shroud fits up perfectly just need to wire it up properly, plenty of people do efan conversions that work fine, you just have to wire it up correctly and have a strong enough alternator. My other suburban came efan from factory btw. Also going to be adding new aftermarket temp guage because you cant trust stock gmt400 guage to be correct

Not worried about it, if done properly they will work fine
