Electric Help turn Signals
« on: January 15, 2008, 12:40:26 pm »
Hi guys, in the process of re-wiring the turn signals & 4way etc due to previous owner having spaghetti hands and only red wire by the looks and it all melted in to one mess.

could someone tell me what colour wire goes into the switch (via flasher can) and which colour for left turn and which for right? I have a new switch with the correct connections etc


The 4way I'll have to wire differently from you guys!!


cheers

I know for sure yellow is your turn signals.. I forgot what the rest where. I'll go piddle around on my truck tommaro and figure it out. I'm having problems with my tails lights as well.

Sorry to bring this one up again but.................

Ok- the 4way works and flashes as it should do.

The left and right turn signals flash a couple of times then stay on. If I turn it all off for a few minutes they work and then stay on again.

The switch and flasher can is new, so is most of the wiring. Is it a dodgy flasher can or in the wiring that I haven't touched yet?

cheers

Did you happen to look at the schematic for your truck?



Guess the image is too big

Here's the link http://www.autozone.com/images/cds/gif/large/0900823d801129cb.gif

Vile yr a diamond! Looks like i can get it sorted from the diagram! is the  "schematic" the diagram? never come across that one b4!

I'm guessing you guys use "hot" as a perminant live? just checking to be on the safe side!!

No that's Paris Hilton  ;D Yes hot at all times means battery voltage, hot in run means when the ignition is switched on. Schematic meaning electrical diagram.
