N/S inner sill wiring harness

Post by guitarman1951 »

Need some help with inner sill wiring. Took the outer sill off my 250 v8, and disconnected the wiring harness under the central B post. repaired the inner sill replaced the jacking points and passenger floor .Ready to fit new outer sill. Unfortunately its been a long ,long job and I have forgotten where the courtesy light wires connect to each other. The inner sill harness splits under the centre B post,and a thick Purple wire and a Purple and white wire coming from the front of the car go up to the courtesy light, and a purple and white wire comes down to the door switch.Ive wired it up the way I think it should be Photo 2. There is no power coming to the light. I think the Thicker Purple wire coming from the front should be the power supply.Can any one tell me if this is so. If so where does it pick up it power supply Also in Pic 1 there is a White wire with red stripe I'm holding it, where does it go???. Im stuck now, because I dont want to fit the new outer sill untill the wiring is sorted.. Wiring is my worst nightmare. Please Help

Hello Brian,

The purple wire is the supply and the purple / white is the wiring that comes off the connector to the interior lights.

LH and rear light operate via their own ring whereas the RH light has a sperate feed. The white wire is for the door light switches.

I had a problem with my interior lights, in so much that all 4x doors + panel switch would operate the RH interior light only. I traced the fault to the supply wire in the LH B post which supplies the juice to the LH and rear light. Taking that in to consideration the RH light has its own feed.

Purple power supply comes from fuse position A2.

The White / Red wire is the solenoid starter switch to starter push switch or the inhibitor switch.

The attached colour wiring diagram should assist.

Regards.

Richard.

Hi Richard,
Thanks for the reply,I've struggled with this for weeks,not wanting to weld the outer sill,thus encasing the wiring. the red and white wire comes from the front of the car, and you can see it in the attached photo,extends for 18" or so with a connector on the end,and nothing to connect it to. Is it coming from the soleniod starter switch, along the inner sill, but then it is just hanging,what does it connect to Wiring is my down fall Ricjhard, your help and patience is much needed and appreciated. The other photo is" I THINK" the fuse box, where the power is supposed to come from, (Is it for both sides) for the interior lights ,although there does not seem to be any power there. kind regards Brian,

Hello Brian,

You are correct in saying that is the fuse box and a useful photo because I can talk that through with you.

The purple wire feeds the cigar lighter and indirectly the horn (via relay) plus the 3x interior lights; you will note that the purple wire has an inline fuse and that is to protect the cigar lighter / horn relay as they draw a fair bit of amps. The interior lights do not need such, directly.

Quite often the best way to check what does what is to disconnect the wire from the fuse box - in this instance if you disconnect the purple inline fuse the cigar lighter / horn and interior light should not work, but will do so if reconnected. I am making an assumption that the relevant connections are secure and working ??

I would not expect the white / red wire - solenoid feed etc - to be in the sill; there is no reason for the wire to be back that far when everything that it covers is forward of the dash. As such, I suspect the white / red wire in the NS sill is in fact the wire to the HRW. It is irrelevant if you have a HRW or not as the wiring was in situ should the option be taken. If this is the case, then the wire will have a bullet connector at the end and is likely to be tied up near the fuel pump.

Out of interest do you have a multi meter that is able to provide a continuity check with the wiring ?? If not it is worth getting one and a good unit can be had for not too much outlay. Failing that you can rig a test lamp.

Secondly, how much of the cars lamps /gauges and other demand items are actually working. Some may be struggling due to the poor condition of the fuse box. In addition the cleaning of terminals and checking earth points (always an issue on classics) can cure many an electrical problem.

The green wires are fused via the ignition, meaning what ever they feed will not work unless the ignition is on - indicators, fuel gauge, low level fuel light etc. This also includes the horn relay, as mentioned above. Have a look at the wiring snap shot I sent you and you will see the significance.

I hope the above assists but in answer to your original Q, you really do need to track down the purple wire feed. This as you have correctly stated splits on the B post and this is where I believe your interior light issue is. I take it the inline fuse is okay on the purple wire ??

Regards.
