I got a little more done this weekend. I didnt have much time, you know, the whole family thing. I did manage to find a little time to make a convertor for my tail light wiring. As we all know the 2nd gen Ex has separate stop and turn signal bulbs... trailers dont, neither do 2nd gen Ranger trailers. I needed a way to convert from 3 wire to 2 wire, and as with the rest of this build, it must be done right but as inexpensive as possible. I figured there had to be a way to do it with just a few relays.
I sat down and did a little thinking and came up with a way.
Parts needed: (total cost...$0.00, I had everything already.)
3 Bosch type 5 terminal relays
3 pigtails
1 fuse holder
assorted elec connectors
I have a schematic all drawn out, but no way to post it. Here's the pin outs for each relay:
R-1 (brake relay):
85- Input from vehicle stop lights
86- ground
30- fused power from battery
87- to terminals 87a on both R-2 and R-3
87a- to terminals 87 on both R-2 and R-3
R-2 (Left turn relay)
85- input from vehicle left turn signal
86- ground
30- output to trailer left turn bulb
87- from term 87a on R-1
87a- from term 87 on R-1
R-3 (Right turn relay)
85- input from vehicle right turn signal
86- ground
30- output to trailer right turn bulb
87- from term 87a on R-1
87a- from term 87 on R-1
I figure with the stop lights off the blinkers will flash in sequence with the tow vehicle. With the stop lights on, the blinkers will flash alternately of the tow vehicle. The trailer lights are all powered off the fused input on R-1, the only thing the vehicle wiring has to do is turn on the relays.
I dont have any pics, and I'm not going to take any tonight. It was too hot and humid today... The power was out for over 6 hours... NO A/C ALL DAY!!
. I'm going to bed.
I'll come up with some pics tomorrow.
Oh yeah, I ordered my tongue box today:
And a coupler handle:
