well after getting more and more feed up with no central locking on my 1989 f70 rocky, bought a kit off ebay!
see this link, these kits are pucker, the seller is good. got the goods in less than a week!
i fitted the kit to my car last night, yep it took me less than four hours to put central locking in my 3 door rocky!
if anyone wants any pics or tips on fitting these things then let me know. it ended up costing me around 25 quid, to put it in and it can be upgraded to a full alarm system too!
im not advertising this seller or these kits, i am just so chuffed that it was so simple and cheap to put central locking in my old truck, i thought i would tell you lot!
