Accessory fuse block HELP!!

[stein]

I went to a stereo install shop here hoping to get a fuse block installed under the hood that I would be able to hook up the following to:
*Oil Pressure guage
*A/F Ratio guage
*Apexi PFC

From what the guy said they realy didn't have what I was looking for. I am a little lost, when it comes to electrical stuff, I am pretty stuipd!

Where can I get something that will allow me to connect the above to a fuse box, under the hood, that turns off with the ign. Also, would 10 guage be good if I am only running it < 5 feet.

you will have to splice a wire into the ignition power wire. I would recommend that you don't do it near the fuse box. You should make sure that you run an inline fuse as well as a proper ground on the chassis somewhere. Off of that you could splice all of you wires for the accessory gauges. Either that or you could get a Moroso Switch Panel with fused circuits, and run the line from the ignition and ground it.....you'd still need an inline fuse..... Then you could setup your gauges to that and leave the switches on. This way they would all come on only when you powered up your car..........however, the easier way of doing things and keeping things cleaner would be to find a tuning shop to install them for you. Electronics is something that you really really don't want to only be 90% sure of when trying to set things up

10 gauge is prolly overkill for that amount of current. 14 ga is probably more than adequate. You also don't want to put a fuse box under the hood where it is exposed to corrosion... c ockpit is where you want to go.

Your not stupid. If ya were, you wouldn't be asking for help/advice.

Usually, you would run one fused hot lead to the Oil Pressure & A/F gauges and split off a leg. The PFC would also get a separate fused hot lead. You can bring both these back to a single higher fused junction strip/block, if ya really wanted to, or you could find a high current POS off the ignition relay and just tie the 2 fuses to that. Current ratings will be specified for each device & are additive. If the total is less than 20A... then the 14ga will probably do just fine. You'll probably only need 16-18ga for the gauges, as they are usually pretty low current devices.

Installing a fuse box is a bit much.

I'm just trying to do it right and thought a fuse box would keep it all clean.

Yeah, after looking at some wire I notice 10 guage was a bit thick! I picked up som 14 guage wire and am now looking into the fuses. Now where can I splice into the + at?

Pin 3 off the IG 1 relay in the center console fuse block or fuse tap the POS side of any of the fuses it feeds.
