    Default can-bus vs old loom electrics

    hi as i understand from reading on here and other places that its not as easy as it used to be to up grade things on the veccy's as it used to be on the eleccy side of things due to can-bus needing signals and having to divorce the old item and Mary the new one to the system with tech 2.

    my point being that on the old cavaliers and other models of the 90's (had a few) that if you had a l base model you could dam near up grade it to a ls on the ellecy side very easy as the loom was there but with out the fuses and the say rear windows controls and ancillaries (depending on your model to begin with) so all you had to do was source the bit from a scrappy and find time to fit and hey presto you had a upgrade with no probs or steelers in the loop.

    now i understand that some things you can but to get the high end things in you need a lot more time and a lot more adaptors and a tech2 and poss a stealer in on it to say ohh you shouldn't be doing that sir while you see pound signs in there eyes!!!!!

    so in summary is this new can-bus a good thing for us all or just the stealer even as the old system was prone to faults but a lot better for puting more ellecy items on your car like after market head units and extra lights with out the probs you get now.

    hi m8
    thiers not a problem upgrading stuff in the veccy as long as you get the parts from close to the same year.i think that what ever a higher spec car has, you should be able to have it in a lower spec veccy.it all depends on the wiring in the car and you need to add.
    mines only an ls and had no extra wiring for the extra toys.but so far i have added heated washers, washer bottle sensor, electric rear windows, headlight washers and a few more but none of the wires where in looms, so i had to had to add them.
    canbus is a good thing as its a very good for looking for faults and checking all is working ok.

    Nowadays many features people take for granted such as remote central locking, fading interior lights, wipers that come on in reverse, steering wheel controls, coded radios and full engine management. Nice LCD displays, memory mirrors, programable locking, auto windows, the list goes on. These all need some sort of control. CanBus is not such a bad idea for these things.

    Also idea like how the vectra uses another light for the brake light if one goes and the bulb warning system would be hard to do and not as good without canbus.

    Can is great (not canbus though as thats incorrect marketing speak) as you can belt shed loads of stuff down a single pair of wires

    In a lovely world there would simply be 3 wires running to the back of the car, 12V and Can-H and Can-L

    plus with say a head unit that is well integrated into the electronic system, means that folks wont want to steal your stereo anymore as its major faff to get working elsewhere.

    yep after reading some of the simple upgrades it looks as easy as it used to like interior lights and sun visors so not as bad as i thort.

    If the stereo controls on your steering wheel are the three buttons each side it's half-can, if they're the scroll wheels it's full-can (unless someone's modded them in).

    Easier than with full-canbus but you'll still need to tech2 a lot of new bits you add (depending what you do).
