Bosch E5000 SPDT (30amp) relay wiring help

[Methodical]

I plan to use this relay to power the following nitrous switches used to activate the N20 devices but need confirmation that it is safe to do (see switches below). Note: All other wiring, relays etc is connected as required by NX wiring diagram and the various components. This question pertains only to getting switched power to the N20 switches used to active the sytem, purge, heater etc. As you are aware each of these devices need a 12v switched source. So to eliminate the need to search for upto 5 switch 12v sources, I want to use the relay so that I only have to tap into one 12v switch source - similar to wiring multiple car amplifers with a single remote turn on switched 12v source. Below is the wiring specs for the relay.

Wiring Specs:

Red wire (30) - to an unswitched 12v source
Green wire (86) - to a switched 12v source
White wire (87) - to positive lead of device to be turned one (each switch I presume)
Black wire (85) - to ground
Blue wire (87a) - not used

1. Is this a good idea?
2. Is a 30 amp relay strong enough or do I need a larger relay? If so what size?
3. What size wire should I use for the White wire (87) on the relay that is to be connected to the power wires for each switch.

N20 switches/devices:

1. N20 activation switch (NX)
2. purge valve (NX)
3. Dual window switch (N20 outlet)
4. Remote bottle opener (NX)
5. Bottle heater (dyno tune)


Thanks for any help.

The only one that concerns me is the heater. I know the heater is going to be your biggest amperage draw, I would feel a bit more comfortable with a higher amp relay , or running the heater on its own circuit. Thats just me though? CALL IT PIECE OF MIND!!

I was thinking of that. What size relay should I go with to accomodate my plan?

Thx

Piece of mind is priceless but most heaters just won't pull that much current. You don't have to worry about using a bigger relay unless the heater is rated higher than 400 watts at 13 volts. Most are much less than 300...

I got to thinking and then I looked at my wiring and I have the heater on a relay already and so are the solenoids. So I now think the 30 amp relay should be ok.


Thanks. sometimes I need a kick start:thumb_yello:
