As I already had the rear of the interior out it seemed like a good time to tackle the rest of the interior pieces I wanted to fit. The SiR headliner, dashboard and carpet which meant I needed to strip out the entire interior to fit them.
Again, never tried this before but after tackling the rear end of the car I was feeling more confident. I did nearly buy a JDM climate control with all the sensors to complete the set but after reading what was involved in switching that over I decided against it. Maybe one day…
I tried to look up info on replacing the UKDM headliner with the JDM one but could not find anything anywhere. I’m used to diving into old forums to find info but there doesn’t seem to be anything out there so I’m going to go into more detail on this part in case its useful to anyone else in future. Maybe it can be pinned somewhere?
So, the main difference apart from the colour is that the map light is in a completely different location. The light units are different as well with the UK one being a single light and the JDM and USDM ones having three lights in the unit.
The first problem was that I didn’t have the light unit, only the headliner and sunroof cover. I started to look around but wasn’t getting very far and was considering trying Jauce, but then by luck I was speaking with the same guy I got the other SiR bits off and he had one that he posted to me along with the pig tail. Due to the location being different I knew I would need to do something with the wiring.
It was also in great condition
I took out the stock one to compare the two and see what options I would have. As can be seen below they are completely different and the connector is also different, one having 3 prongs the other 4.
After closer inspection even though the JDM one has a 4 point connector it only actually has 3 wires going into it and they were the same colours as the UK one. I soldered some small spade connectors to the end of the pigtail wires and tried to put them into the UKDM female connector and luckily it worked. Both the light for the doors opening and the individual map lights functioned correctly.
I didn’t want to cut up the wiring as I do want the option to put everything back to stock. I am keeping all of the parts that come off the Prelude so I wanted to try and come up with a solution that didn’t involve cutting it up. Next was to remove the headliner and see if I would need to extend the wiring.
It wasn’t as bad a job as I thought it would be, I found a good guide online.
After some tracing of the wiring for the light I found it goes from the front drivers side A pillar along the side of the sunroof frame and then comes around the back of the sunroof to the centre of the roof along with the sunroof motor wires.
They are just taped together so I manged to unthread the light wires and then unpick them from the rest of the bundle.
I did this all the way back to the top of the A pillar then rerouted them along the front of the sunroof so they finished up near the rear view mirror. I taped them all back in place and then reconnected the pig tail I added the spades to into it and taped them in place so they wouldn’t come back out. The JDM connecter was then in the correct position to thread though the new roof liner once it was in place.
Once the wiring was in place, I fitted the headliner in there being careful not to bend it. Most of it is held in with the screws for the sun visors and mirror/map light, 3 clips along the rear windscreen and then one circular clip in the centre of the roof.
I don’t have the red sun visors yet so just put the grey ones back in, I did paint the circular clip red but haven’t got a photo of it in there. I am arranging for some red sun visors to be sent over to me from Europe but since the massive f**k up that is Brexit it difficult to arrange postage.
