Relay Diagram No10 Four Wire Reversal

This diagram clearly states at the top that the diagram can be used when both motor legs of the door locks are normally open. Can this diagram be used or adapted when both relays rest at ground? Thank youShaun

Thanks,I already have tried that one.The result is that the motors,when operated via the remote keyless entry are very weak,although they do move.When the motors are operated by the factory switch they are strong and fast operating The only change I made to the diagram you suggested is a positive trigger from the RKE unit to 86 with a diode across to a grounded 85 to both lock and unlock relays. There are only four wires at the switch. Shaun

Before you try this, let us know what vehicle you are dealing with. https://www.the12volt.com/relays/relaydiagram3.html

Thanks, it's a UK spec 1998 mitsubishi L300. The van was equipped with factory actuators wired to a factory three position switch. There are no relays that I can find (or hear). There is nothing wired into the drivers door so I opted for two relays as a preference.Shaun

Was this information helpful??Shaun

It being a UK vehicle I do not have any wiring info on it. If there are no relays between the switch and the actuator, the above link I provided should be what you need. It is ok to use 86 as positive out of your unit and ground 85. But you do need to supply 87 with a high current capable positive.

Thanks, I'll check it...Shaun

I have a length of 10 gauge stinger OFC cable leftover from something else. I would think this would satisfy the requirements at pin 87 direct from the auxiliary fuse box??Shaun

Yes, 10 gauge is more than sufficient.My ex once told me I have a perfect face for radio.
