Here's the same diagram with added handbrake interlock:- 36C_lights.bmp

that's great! i have another relay hanging around somewhere and would be useful for the handbrake. thanks much again. now i have to get some h1 harness so as not to destroy the oem in the car. i think i have a 15 amp fuse coming from the ignition, do i need another inline coming from the park light and what rating should it be?Noob Forever ....

No, only the diode. That relay only draws about 1 amp, shouldn't affect the load on the lighting fuse.

again, i cannot thank you enough. will be working on this as soon as i get my harness :)Noob Forever ....

sorry sir to come back with a noob question again - i just want to clarify that should i be looking to tap from the negative of the handbrake warning light in the gauge cluster harness?Noob Forever ....

Yes it's switched NEG, alternatively the wire from the handbrake.

thank you sir for that clarification, i already looked at my car's diagram and its a GREEN/ red cable. but before i do any complicated wiring, i just finished the basic one and i ran into something odd - the drl works when i turn on my park lights instead of vice-versa. is there too much power from the lights? not enough power from IGN? are the relays (i already tried two of them with the same result) damaged? i also put a diode but 1N4148 'cause i cannot find the one on your diagram i.e., 1N4004 - is that the problem? please help. sorry again for bothering you.Noob Forever ....

4148 isn't suitable but check the relay wiring.

I just checked that diagram again, it's confusing! Square on left, "+DRLs" is going from the power source for the DRLs, switch etc. Bottom right feeds them.

wiring sir is as per diagram, i even tried reversing 86 and 85, and putting 87a to 87, and 30 to 87a. could you kindly please explain how would the diode affect how the relay should work for my added knowledge? thank you sir, i will try more to look for 4004 tomorrow.Noob Forever ....
