live wire for elec oil press and temp

[the lemster]

anyone got any ideas as to the best place to cut these wire into...  I ahve used the dimmer switch for the ilumination but need to others.. live and earth/neg for them aswell...  somebody mentioned the aircon relay.. is this practical... any other easily accesible suggestions... the gauges are mounted in my spare din socket... so anywhere around there would be bonza

as this is a little [project of mine I will try and post up pictures and stuff... I am using a oil take off plate ( sandwich plate) to run the senders from...

have all the bits just need the electrical side of things sorted....

cheers

How about a cable from the ignition? The live wire that is live when you turn the key? Or one from the radio loom?

[davehg]

earth it to the same point as the radio

[the lemster]

do you have any colours for these wires...

and is the ignition live easy to get to without taking anything apart... from underneath?
can I run two other wres from it?...is it fused?

can I take the  lives from the radio loom?...same as above fused etc.

[nikp]

I would expect them both to be fused. What fuse though, i don\'t know! Sorry!

As for colours - again not sure, but if you have a voltmeter, it should be a case of tuning the ignition on and finding a wire with 12v off the ignition barrel (Or radio loom). Then turn the ignition off, and the reading should be 0v - I wouldn\'t have thought you would want a permanent live as you\'d end up with a flat battery after a few days. You would probably want the switched live wire.

If you want a radio loom wire colour, you may be able to trace it if you have an installation guide for a radio. Trace the live wire from that and find the equivalent in the actual loom.

take the live from any switch really - or fag lighter - they wont take much votage

[the lemster]

how do I get to the fag lighter wires....

up undert the dash I suppose....

anyoone know of a \'HOW TO\' PAGE...

I ahve down loaded the \'iluvmyrx7\' wiring diagram but havent looked at it yet as I only have adobe 4 at work... need to get it home...

but a definate how do fo rthe install wuld be great...

cheers

i have no idea to be honest - the FC was easy

does the dimmer switch have a live feed ??

what about the back of the radio ??

[nikp]

lemster, i\'m in bristol and have had the dash panels, etc off so am reasonably happy with the electrics back there. Also have a voltmeter (somewhere! :p) If you fancy coming down, say, sunday, I\'m happy to give you a hand finding a suitable wire. Should be quick to do - I had to fix the dimmer on my boost gauge cos when I first installed it it dimmed when the rest of the dash lights brithened! So have been back there before!

[the lemster]

ok ready to laugh....

I managed to take a live feed from the radio power lead... and I have earth it through the  dimmer switch... is this bad news?... havent connected it up yet just wired in the wires if you like....

NIKP... do you work at airbus.... my wife sees a rex with a body kit and zaust on nearly every day....

[nikp]

I\'m not entirely sure that\'ll work - I believe the ground on the dimmer switch is the one that controls the brightness of the lights. Not 100% on this though, but you may find a drop in voltage to your gauges. Unless you\'re using those for lighting, in which case it\'s perfect.

Nah mate, i don\'t work at Airbus. Do just live down the road a bit from one of the Airbus offices though! :p

[the lemster]

no nor am i... but it is wortha  shot aint it.... at most I will blow a fuse...

just though I could just earth it to the body of the car couldnt I!!!

[nikp]

Yup - earth to body will do it. No question about that one!
