Keyless Entry + Audio System + Dome Light

Hey there everyone! I'm new here, and I was trying to look for this for sometime but was unable to find anything valuable. So basically I have this Toyota Hiace (classic) and I want to couple the keyless entry system with the audio system and the dome light. 1. I want the dome light supervision when I unlock the vehicle and turn off with a delay. 2. At the same time I want the audio system to power up and keep working until I get out and lock the vehicle. Is this possible? If so how?? Please help me outThanura Weerage

You looking to do "Dome light supervision" And "RAP" (Retained Accessory Power) until doors are opened. Plenty of info on this site just need to search for it.

Thank you so much. Ill have a look. But how to link these together?? I lack knowledge on these areas. :/ Can anyone help with me with few diagrams and stuff? PleaseThanura Weerage

And no, basically, what I want is, when I press UNLOCK on the remote, the stereo to turn itself on. and when I press LOCK, I want it to turn off. This should be constant. IN RAP, it turns off after 10 minutes. This is exactly what I mean.Thanura Weerage

You can try this for starters.

Or this. RAP Diagram

Or a modified version of this with the lock and unlock outputs from the alarm and diodes. to have a on\off +12v Single Pulse to Lock and Unlock (link) Using a mechanical latching relay like the PCB latching relay pictured below on the left, you can use a single negative output to alternately lock and unlock the doors. The mechanical latching relay only requires it's coil to be momentarily energized to change and maintain the opening or closing of it's contacts. The SPDT relay will provide a dedicated negative output for lock when the coil is energized and a dedicated output for unlock when it is not energized.

Single 528T timer relay or similar will suffice. Trigger from unlock wire which will have a NEG trigger in the driver kickwell if the locks are OEM.

Forget it, you will need either an extra relay for either ACC or dome trigger! Or use a trannie to change polarity since the radio needs a POS and the dome needs a NEG.

@howie II I don't get why he wants it wired the way he does but, he wants there to be no timer to time out and shut down the radio. "This should be constant. IN RAP, it turns off after 10 minutes." That why I made my last suggestion of a modified version. Hint hint! LOL
