Daytime Running Lights

[1989 Mark 7]

I heard that some gen 2 Mark VIII's have daytime running lights. I know that the lights come on automaticly but never known them to have DTRL :V

my 93 markviii's headlights only come on when its dark.

i actually need to install DTR in the 94 mark i just imported - anyone know how easy this is to do?

I think only the canadian versions had dtrl

yeah, i imported an american car to canada, so if anyone has any idea of an easy way to do this (i have heard it;s just a relay) i am all ears.

I'll look in my manual when I get home to see if I can find a schematic

You will need the DRL Resistor, and the DRL Module. I do not think you will need the wiring harness because the factory usually runs all the wiring it will need no matter what.

What I would do is call Max at 5 Star Ford and see if he can get those parts, and I can help you with where you need to look to put those parts into the car. Max's number is 1-800-866-1520 ext. 236. :Beer

ditto...

The wiring should be there, just the 'module'(relay) and the resistor. I've never personally looked at my '93 to see if that's so, but I know the wiring diagram shows the wiring/harness plugs for the DRLs.

i appreciate all of the help guys

No prob....that is what we are here for. Glad we could help. :Beer

 

[67Continental]

Ok, i had the DTRL installed by Ford, but now i get the "check exterior lights" warning from time to time. it's really irritating - what can I do?

 

[driller]

The quick and dirty way is to snip a wire. If someone else doesn't chime in, I'll look it up in the manual at home.

 

[67Continental]

which wire do i need to snip?

 

[driller]

From the '93 EVTM, the lamp out warning module communicates to the message center via circuit 130(red wire with light green stripe). Pins 5, 7 & 8 of connector C227 of the lamp out warning module are connected to splice S273 and continues on to pin 6 of the message center connector C246 - the lamp out warning input.

 

[67Continental]

so if i cut the circuit 130 wire it should work? will the computer interpret the lack of communication as a light failure?

Yes, it should work.

No, the lack of communication between the modules should not be interpreted as a light failure. If it follows operational characteristics of other systems, the 'trigger' wire is switched to ground causing a warning to be given. I tried to find definitive language of such operation in the EVTM but could not.

You could play it safe and sever the wire in a easy place to allow reconnection. :wrench

thanks for your help. you don't happen to have a diagram, or know where I could find the wire under the hood do you?
