relay for hella horns
hi guys,
just got a nice set of hell supertones from scoobypart.com and was wondering the easiest way to fit them or more to the point to wire them up...I have the relay and the wiring diagram says where they go etc but looks all a bit strange so my question is this...... could you just disconnect the horn already on the car and then wire the 2 hellas in place with the relay between them or do you have to run a supply from the battery etc
any help or advice on a good quick easy way or a good way of just doing it would be good....
I know where to mount them so that's not an issue just wiring them up...
thanks guys

Personally, I WOULD use the relay.
Two reasons: the stock Scoob wiring is poor, and the new horns pull about four times the current of the old.
Wiring as follows:
Relay terminal 85: from old horn.
86: to a suitable earth.
87: to new horns.
30 FROM battery +ve via a suitable blade fuse.

Second horn is in front of the RH (offside) wheel behind the liner.
Standard relay is fine.

Blobeye needs the relay setup as the horn circuit only has a single feed from the relay to the two horns and the fuse supplying it supplies the following circuits as well:-
Cruise control sub switch
Hazard switch
Keyless entry control module
Key warning switch
Security control module
Blobeye OEM
Hella Instructions
Simplified Hella install

[QUOTE=Don Clark;11722553]Hatch onwards doesn't require a new relay setup as the horns are on a separate circuit with two feeds direct from the relay so the wiring is man enough for the job

thanks for all of this info ... so if my hatch has relays already installed would I be right in thinking the lead from my current horn goes to one of the connectors on the new hella horns and the other connector goes to ground.... the connectors on the hella horns are labelled 30 & 14.....

Doesn't matter which horn terminal is which.

I bought my kit from the USA, subimods.com glad i bought the wiring kit and bracket, so much easier to fit.
