Hilux - Wiring

[ChrisF]

I want to provide 12V to the fridge in the back of the Hilux.

Running the wiring was the easy bit.

I opted to go for a relay to cut the power to the fridge when the ignition is switched off.

Here's the question - WHERE is the easiest to pick up a 12V signal that the ignition is on or off ??


In my previous vehicle I used a signal from the sigaret lighter - not easy to get to in the Hilux.

Do I have to fiddle under the dash, or can I get an ignition ON/OFF signal inside the engine compartment?

Off the coil in the engine compartment.

It is a 2,5 Diesel.

any other spot to use?

Oh. sorry man!

If you have a multi tester you can check the fuse box in the engine compartment which fuse terminals come on with the ignition and run a cable off one of those supplies to your relay. There might be one marked "Engine" ..... don't know the SRX .... you'll just have to check. Use the one with the highest amp rating you can find that comes alive with the ignition .... It might be better to find one that comes alive on the accessory position so that you have the choice to run the fridge without the motor if you should ever want to do so.

The manual is your friend ...... (well almost)

The manual points to THREE fuse boxes:
1) In the engine compartment
2) Behind the glove box
3) Under the steering column

BUT, to get to number 2 and 3 parts needs to be removed ....
- The glove box just clips out
- A panel under the steering column clips out.

The second column, once removed, reveals the back end of the sigarette lighter. :D

Let the pictures tell the rest of the story -

The cigarette lighter feed should be ideal (They usually work on accessory) and the relay won't draw enough to interfere with the normal lighter operation. Run your trigger wire from the lighter feed through the firewall via an existing cable gland / grommet to the engine compartment and bring it close to the battery. Mount your relay in that area and leave a little slack on all three live's (• Main live feed from battery, • switched live to fridge, • live trigger). The fourth wire required is of course the earth. Should work like a charm!

Mudd Dog - presies so gedoen. :D

Drade oorals mooi gecable-tie. Positiewe drade beskerm teen moontlike vibrasie teen metaal oppervlaktes.

Lugs mooi gekrimp - mooi Hellerman crimping tool gekoop vir die jobbie.

EN, laat ons nou nie vergeet van die "in-lyn" sekering (fuse) nie.

Laat ek dit SO verduidelik:
Jy kry n paar opsies om die yskas aan die gang te hou
1) tweede battery - beste en duurste opsie
2) koppel die yskas aan die voertuig se battery ..... dis nou hier waar dinge interesant raak.

AS jy die yskas lank genoeg laat loop gaan die voertuig se battery pap trek, dit kan die battery beskadig EN jy het probleme as daar niemand is om jou te jump start nie.

So nou vat ek die maklike pad. Gebruik n relay wat slegs krag na die yskas stuur solank ons ry. Dit werk goed wanneer jy kamp waar krag is .... Sou jy lang tye sonder krag wil kamp - wel dan moet jy seker weer kyk na n tweede battery ...

Dankie Chris,
Ja, dit maak sin - ek sit met 10 duime wanneer dit by enige bedrading kom! :wth:
