who wants to do this for me?

done everything apart from the LH indicator and side light. Some reason the right hand sidelight won't illuminate. Will hook up left and see if there is an issue.

twisted and soldered... Electrical taped for now... But will heat shrink when working correctly... @Enuo @h701micra and @lowrider is this count as a bodge

Ta dude there is a slight change in wire colour here and there as the looms been repaired. There seems to be the req of two rear side lights .. Obvs two power supply less strain on wires. Uses the whole of the 6 core that way. I was thinking there may be a need for them both of them to be live to work. But that would make 24v no? So I rekon trailer is dodgy.

tried that thing all the scene kids are doing... Well didn't like it. Looks stupid.

here is my in car computer / extra ECU / instruments cluster and data logger with arduinos and direct ECU connection gubbings to go along.
 
You log as many as you want depending on a few factors mainly... Processing speed, bandwidth of com lime and latency or speed of you will of read write speeds. What do you want to do
 
Trailer lights all plumbed in and buzzers working. Ended up re wiring the trailer in the end... Bloody ****e wiring. Tis old I supppose.

I think Andy is thinking of reading pots, so needs to measure 4 variable resistances?

Pots? Hmm you might be able to but my electrical knowledge is still basic. You can input ranges between 0 and 5v so whatever you got in there cool

Simple potentiometer readings but many of and the signal converted to a value i.e distance :)
 
You'd supply a 5v feed to the pot, and get a varying 5-0v output dependant on resistance. You'd then need to calibrate it by manually measuring the displacemnt, measuring the voltage and plotting a graph. If you use linear scale pots it should be a straight line, and you can simply work out the ratio of volts-distance. Log scale pots are more complicated...

Lol yeah so that's what I said but like better
 
The data logger I have takes 6 readings at once and I don't fancy another £400+ bill to recreate it again

Works exactly as you've said. 0-5v. As long it can log the values. And we can manually convert them to our units

Get graphs like so

Which is ok but I need 2 extra channels to create a full movement vs compression graph to see the affects of dynamic roll centre and how they affect even 50/50 balanced cars

Just towed and weighed in 600kg odd ... Literally... of metal/pcs. the car didnt batter an eyelid apart from stopping lol that was fun
 
Also a crazy bi product of the tow bar. So.. I got it on and took it out for a drive. The arse end feels great all of a sudden. The ass is more planted and just feels more positive. Weight at the rear... Plus.. Chassis strengthening.. The tow bar is not light and literally pulled the chassis rails and rear floor pan back to shape when using a breaker bar to get everything sitting straight.
 
I struggled to get the bolts nipped up and had to work them all up. Great fun. The car seems less of a burden now... Its uses are more practical and makes more cho cho noises with the load. I made enough money to pay off the tow bar today. If anyone has seen my garden before.. its now starting to look clean.
 
Back to logging :D
Andy, a large consideration is the required frequency of logging. I assume the pots will be wheel displacement? Will need a high frequency logger IMO. A few hundred Hz
