Instead of having music tell us how it works. Note that each pin is numbered. 85 and 86 are the coil pins while 30, 87, and 87a are the switch pins. 87 and 87a are the two contacts to which 30 will connect. If the coil is not activated, 30 will always be connected to 87a. Think of this as the relay in the Normally Closed (OFF) position. 85 goes to the power window swtich which connects to ground. When 85 on the left relay is connected to ground 87 connects to 30 placing positive down the blue wire to the motor. The right relay is at rest so 87a is connected to 30 causing negative (ground) down the purple wire to the motor. When 85 on the right relay is connected to ground 87 connects to 30 placing positive down the purple wire to the motor. The left relay is at rest so 87a is connected to 30 causing negative (ground) down the blue wire to the motor.

Fantastic and very informative sir. Never seen before these type vedios
whould you tell me what gauge wire are u use from motor to relay, relay switch and wire gauge for ign sw and batt wire gauge?
what is the wire gauge are u using for power, ignition and wire goes to switch and motor?
thks❤️
Good video ❤
Thanks 😁

So the two 85 goes to switch like ground ?
I was thinking the same, i think yes because the ignition cable will be the positive, throwing the negative on the 85 you will close the circuit
Where do 85 (switch)goes to positive or negative
Every time I do it the relay become the source of using power. Since the relays in the middle
Uae number 87 as a power supply
Make another video on this in full detail.
Yes sir
Which wires connect to the switch??
85
Full details video
you shorted the terminal 87positive and 87a negative this is wrong diagram
Right diagram send karo
I TRIED. DOESN'T WORK. SHORT CIRCUIT.
Use relay with 87a instead 87 and 87
