Orgasmic Farmer Posted July 26, 2008 Share Posted July 26, 2008 I am currently wiring in the difflock actuator on the Nissan axles under the discovery and am using the workshop schematic below as a guide. However I do not have a 2-way switch as shown and short of a 30 mile drive to get one or wait for a delivery am stuck at an impasse. However I do have loads of various relays here and i had a brainwave that perhaps I can replace the 2-way switch with a relay (switched by a simple 1-way on-off switch that I have here) that will sent the current either way depending on whether it is open or closed. I am sure such relays exist I just need to identify them. Anyone out there can confirm that this will work and help me find what i'm looking for. An idiot -proof wiring diagram would also be helpful! cheers Mark As you can see I am useless at electrics! Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted July 26, 2008 Share Posted July 26, 2008 A standard auto '5 pin' relay, with 'normally open' and 'normally closed' contacts will do that. they'll be labelled 87 and 87a. Quote Link to comment Share on other sites More sharing options...
Steve 90 Posted July 26, 2008 Share Posted July 26, 2008 Any 5 pin change over relay ( as Landy man luke^^^^^ Said) will do it or I have the exact switch you need, I'll chuck one in the truck when i come over. Just make sure its a change over and not a 5 pin with two common outputs. Quote Link to comment Share on other sites More sharing options...
ThreeSheds Posted July 26, 2008 Share Posted July 26, 2008 I reckon there is a way with a switch and two normal 4 pin relays, but I am struggling to work it out... I'll let you know if I get it... Edited: Sorry - I think that perhaps I am wrong. Unless somebody clever knows otherwise? Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted July 26, 2008 Share Posted July 26, 2008 Just make sure its a change over and not a 5 pin with two common outputs. Yes, you need 87 and 87a, not 87 and 87b. I reckon there is a way with a switch and two normal 4 pin relays. You could use two normal relays and switches, you'd just have to switch one off as you switched the other on - far easier to use the proper switch Quote Link to comment Share on other sites More sharing options...
Orgasmic Farmer Posted July 26, 2008 Author Share Posted July 26, 2008 Have a relay with 87 & 87a on it now and have done a trial and it looks like it should work OK cheers for all your help Mark Quote Link to comment Share on other sites More sharing options...
Orgasmic Farmer Posted July 26, 2008 Author Share Posted July 26, 2008 All wired up and it works a treat. Now have a vacuum locker on rear axle with dash switch and light in cab... All I need to do now is shorten the props, rebuild front axle and plumb in the brakes.... and hope for the best! Quote Link to comment Share on other sites More sharing options...
