Location for relays for fan fuel pump etc...

[HandOverFist]

I have everything mounted behind the glove box door...switches are on the driver's side.





For some bullet proof/compact components check out Leash Electronics... http://www.leashelectronics.com/

Thanks that is exactly what I was thinking.

Yes, all nice and neat looking, but DC power diminishes with wire length.
Also, as stated , the w/p and fan both use a bunch of amps.
Best to keep the the wire large and the run short on those items, in my opinion.

Mark, I value your opinion. I was also thinking of making a small board and mounting it to the upper flat section of the driver's firewall

Here's a link to some good info and a wire sizing chart http://www.yellowbullet.com/forum/showthread.php?t=431340&highlight=wiring+skills Do yourself a big favor and buy a lot of different color wire and also make a wiring diagram. At home it's no big deal to trace circuits, at the track it's frustrating.

Putting all those relays together in the glove box or on a piece of aluminium in the driver's compartment sure looks nice and tidy. Guess what happens if your fuel pump self destructs and dead shorts. I'll tell you, your heavy feed wire to the pump will fry all the way back to your fancy relay panel melting every other wire it's close to. How would I know that?

All my circuits are fused no matter what amperage they run. I have a breaker in the main power distribution block, too. It shut my car off when I floored it once. Something big shorted out. Nothing burned. Same for the fuel pump. Shorts pop fuses.

Same here...everything fused and fused correctly. Funny, why would anyone take advice from someone who admitted to burning his junk down?

That's why everything gets fuses or a circuit breaker for protection. I've seen the burned wire to the fuel pump on cars before, no fuses and some had no relay. I don't class race and my battery is in the back. My fuel pump and it's relay are in the back also and both circuits to the relay are protected. Also my fuel pump ground goes directly to the battery, not a sheet metal screw into the floor pan.Nothing increases current draw like a bad ground.
