Where is the wiring loom in a honda jazz?

jeepers101

I think its called a wiring loom anyway. Need to fit a keyless central lock unit. Haynes manual and google not throwing much up.

The wiring loom runs through out the car.

Does the car have central locking? If it does google for the central locking control. If no central locking it's a big job to wire all the doors.

If you think its called a wiring loom and you cant find it and want to install a keyless central locking unit, take my advice, DONT.

Get someone who knows what a loom looks like and who is familiar with auto electrics

That's not the first time someone on this forum has told me not to try something. How about helping a guy out rather than telling him not to try it. It's amazing what people can achieve when they put their mind to it.

Yes the car does have central locking. I googled that but it didn't throw much up either.

I read one of the amazon reviews for the kit I have and the fella said he spent 20 minutes in the wiring loom with a multimeter and had it sorted. If I can find this wiring loom I shouldn't have a problem.

Okay the wiring loom runs through the car. So firstly remove the pillar trims then the dash, seats, carpet don't forget the door cards. It will look a bit like a snake made of wires and be routed all around car. Hope that helps

I would have thought there'd be a place where all the cables are terminated, somewhere I can stick my probe in. How else will I test what cable is doing what?

As per other posts you seem to know so little about the subject you would be better off leaving it alone would you try brain surgery just by reading about it ?

Seriously? Brain surgery? Not really a fair comparison. If you don't know that's fine. No need for you to post.

Fair play Jeepers..... Don't think this one will end well.

corktina

seriously, if you fry your loom you've pretty much killed the car , take it to a professional autop electrician

Just saying you are out of your depth her e so would be well advised to leave well enough alone

I think that poster meant that car electrics can be quiet complicated and if you don't have much knowledge on the matter you could be just doing more damage than good. You could end up frying any number of expensive components like the ecu..etc.

I think they really were just trying to help you rather than have a dig a you.

I reckon you should go for it OP.

Never mind the neighsayers.

Right I don't know any auto electricians and I'm too cheap to bring it to a garage so I'm going for it. Maybe tomorrow. Will update later.

Check where the central locking control is located. It should be in one of the doors, but may not be. Easiest way, apart from finding a wiring diagram somewhere on the net , would be to follow the cables back from the door lock till you find a box with a few different feeds going into it. Or try on a Jazz forum

Yeah, it's jazzzz, just improvise!

You don't need a terminating point, just pick a part of the loom that's easily accessible and cut it. You can then test each wire individually with full access to all the copper strands.

When you're finished you can just glue or tape the wires back together. No need to take the seats and carpet out Knifey, that's using a sledgehammer to crack a walnut!

OP, if when you click on the link above re wiring diagram you can figure out where on that diagram or what line you need to be connecting into, then I say fire ahead. You could then look online for detail of where the particular wiring is located or what colour or shape the particular connector is.
If you cannot make head nor tail of the diagram, you are onto a loser.
What exactly are you trying to do? Does the kit come with wiring instructions?
I guess you will be looking to tap into a circuit that is only powered under certain conditions, Multimeter testing is the way forward there but test wires at location where you are not damaging the connections or wires. I dont like the idea of piercing wires with the multimeter either. Also be sure not to send 12v power onto any delicate electronics.

seeing as he didn't know what a wiring loom is, is it wise to be advising that? I wouldn't do that and I DO know what a loom is.

Yeah I can make sense of the diagram alright. I know I need to send a signal to the Gn and Lgn/Rd connections on 121 and 120 respectively.

The only thing that might trip me up is making sense of the diagram that came with the kit. Looking at the positive trigger section, there are a couple of cables labelled "Non-connect". Does this just mean I don't connect them? Also the two "+12V" on the trigger; can I just loop these from the battery?

I assume the "Lock signal" and "unlock signal" are the output signals to the relays.

Positive trigger susyem

C14 Green to the unlock signal
C30 LGn/Rd to lock
White is the original permanent 12V supply that you can use.


*BE VERY CAREFUL* Item 65 is a control unit which may be very expensive if you fu(k it up.

Would it be wiser using the negative trigger system then and connecting to D13 and D14? 132 is the Driver's door key switch.

After reviewing my post, i deleted it as soon as i posted it as there are too many other variables. Do not use.

jeepers101

Turned out to be pretty easy in the end.

For anyone else with the same problem in the future I did indeed go for the negative trigger option and connected it to the driver's door key switch.

I took the panel off the door as seen in picture 1 to confirm the colours as seen in the Haynes wiring diagram.

Then I followed the cables to underneath the driver's side fuse box. I took a couple of panels off above the pedals for better access. Picture 2 shows the connector to which my pair of cables go to.

Picture 3 shows the two cables cut. I connected my unit with these cut cables and hey presto. I didn't bother connecting the key switch back up as the whole reason I had to do this is because the key switch has seized.
