Rob_Quads Posted January 7, 2010 Share Posted January 7, 2010 This guide is based on you purchasing a BOSE Steering Wheel loom (29-674) and Head Unit Specific Adapter (29-001 for Alpine). Below is a picture of a typical loom you get with a head unit Plug A connect to Head Unit Plug B connect to Plug D on ICT loom Plug C Is not used (this is the speaker level output from the stereo which is not required with using a BOSE Amp) Wire J connect to Wire G on ICT loom Plug D connect to Plug C on ISO loom Phono Plugs E connect to the Front and Rear Phono outptut on the head unit Plugs F connect to the Nissan plugs behind the dash (Top one is for steering controls, bottoom two supply power and feed BOSE amp) Wire G needs to be connected to the Wire J on ISO loom Wire H need to be connected to ground (this is the amp ground) Plug I connect the Head unit specific adapter i.e. 29-001 To connect the Steering Remote section connect the loose cables as follows. The colours 'sometimes' vary by if you follow the picture of the plug its always the cables marked A, B and C ICT Unit white Cable -> Red/Green Cable ICT Unit Grey Cable -> Orange/Silver Cable ICT Unit Purple Cable -> Yellow/Green Cable There is also a final step which is required which is to connect up an extra ground lead. The standard BOSE unit is ground through the casing to the chassis. As a result the ISO loom does not have the normal ground. This must be added manually Quote Link to comment Share on other sites More sharing options...

Rob_Quads Posted January 8, 2010 Author Share Posted January 8, 2010 The three white cables plug into the cables that you removed from your BOSE head unit Quote Link to comment Share on other sites More sharing options...
Burnsidea Posted January 8, 2010 Share Posted January 8, 2010 The three white cables plug into the cables that you removed from your BOSE head unit Have they sent me the wrong loom as I don't have F. see both pics Quote Link to comment Share on other sites More sharing options...
Rob_Quads Posted January 8, 2010 Author Share Posted January 8, 2010 Might be worth emailing ICT about this as i thought the 3 bare wires should have a connector on the end (to connect to the one you have left) these are for the steering controls tho so won't affect the unit not working.

Rob_Quads Posted January 8, 2010 Author Share Posted January 8, 2010 Have you spliced in an extra ground lead to the ISO lead? 1 Quote Link to comment Share on other sites More sharing options...

Ekona Posted January 8, 2010 Share Posted January 8, 2010 You need to find the ground wire on the ISO loom and splice a wire into it to the chassis of the car. The Bose loom as standard has no earth, and without this wire you'll get no power at all. Quote Link to comment Share on other sites More sharing options...

Rob_Quads Posted January 8, 2010 Author Share Posted January 8, 2010 Find a nice metal bit of the car - there are a few points around behind the stereo. Generally most screws that go into the chassis will work. Take a wire from that and then cut into the black ground cable in the ISO loom and connect it up. Have you tried putting in the aerial (this is only good for a check) - this should provide enough ground to get the unit on. Those connections look about right Quote Link to comment Share on other sites More sharing options...

Rob_Quads Posted January 8, 2010 Author Share Posted January 8, 2010 The one that goes into the head unit and gives you two ISO standard connectors i.e the brown and blackones Quote Link to comment Share on other sites More sharing options...

Rob_Quads Posted January 8, 2010 Author Share Posted January 8, 2010 yup - you don't to cut it just strip back the coating over part, solder on another cable and tape it all up (or heat shrink it) Quote Link to comment Share on other sites More sharing options...

Ekona Posted January 8, 2010 Share Posted January 8, 2010 What don't you understand? Find the earth and tap into it: How hard is that to do? You're basically just teeing into the wire and extending it so you have an earth going to the head unit. Without trying to completely patronise you, do you understand how the earth works and why it's needed? Quote Link to comment Share on other sites More sharing options...

Rob_Quads Posted January 8, 2010 Author Share Posted January 8, 2010 Hace you tried the aerial trick I mentioned? (can't help any more for a bit as I am snowboarding) Quote Link to comment Share on other sites More sharing options...
hotwire0001 Posted January 13, 2010 Share Posted January 13, 2010 Does anyone know where to get the 16-pin socket that's missing from the ICT lead. I have contacted them and they say the reason they no longer fit this is because they can't get hold of the part any more!!! Or is there an alternate lead ??

chrisballuk Posted June 30, 2010 Share Posted June 30, 2010 just noticed direct from incartec.co.uk they are supplying the 29-674 adapter in 2 types, hard wired and plug and play that includes the plug F. Also noticed they have double din fascia that does not need to have the middle cut out. Will let you know when I get my car and get the JVC DD installed Quote Link to comment Share on other sites More sharing options...
