Does anyone know what the differences are between a Blackjax 4 and a Blackjax 5? I know the 5 is the later model but I have seen a new boxed 4 for sale at a very good price. Steve

 

I decided to buy the Blackjax 5. Got it for £77.99 + £7.99 delivery. Steve.

 

how easy are they to fit, as was thinking of doing this myself

I had one fitted to my last impreza by a Clifford alarm installer. I would not attempt it myself as after doing a search I read of people having problems with the unit because of incorrect installation, so I would advise professional fitting. Steve.

 

fitted mine myself and the only problem i had was the factory fitted plug that connects the wires to the unit, it got hot burnt the contacts and melted the plug itself so cut it out and soldered the wires back together and never had a problem after that.

 

Fitted today. Great job. Thanks Jack. Steve.
