Recommended Posts

I'm busy fitting my dash2 to the supra and could do with a little help please.

 

Does anyone know what colour and which of the 3 speedo cluster plugs the following are please

 

1) rpm signal wire

2) speed signal wire

3) handbrake or MIL light

4) alternator/battery charge warning light.

 

Thanks

John

If you want the brake light to only do the handbrake/brake warning light and want the '!' light as a seperate one you will need to fit an additional LED just for the '!' See picture attached.

 

The Alternator/charging wire is up behind the Odometer from memory - Think it is the Yellow/Green wire.

 

For the full beam you need a relay to get the light to work correctly or it will be on all the time with dipped lights.

 

Pic attached aswell.

 

Which ECU are you using? If its the Syvecs you can use the CAN adaptor to get the RPM's and Speed from the ECU.

That's great steve thanks buddy.

I will be using a solaris ECU. I think I'll just run the RPM and Speed signal down to the ECU loom be easier than tracing wiring.

 

I wondered why the full beam stayed on all the time when the lights were on and would work fine when dipped were off. Have you got a diagram by any chance on how to wire the relay for main beam.

 

I don't mind using the handbrake light and MIL light as 1 to be honest as that's how it was with the stock dash.

There is a pic attached in my earlier post for the full beam relay. Just needs to be a cheapy 12v relay.

Got it cheers for the help steve. I'll get the relays, and a 4 way toggle switch for the menu functions from maplin next week and get that part finished off.

 

I was dreading fitting this but seems to have went quite well with a little help of course lol.
