how to wire lilliput into a molex

Froogle · 05-19-2005, 02:58 PM

Hi guys

can you please give me some advice

I have a lilliput touch screen monitor and want to cut the cigarette lighter plug off and attach the wires to a Molex connection which runs to my psu.

when my carputer turns on the monitor will get power, how do I do this ?

Cheers

Doing some

would do you some good, but here is your answer. The Lilli runs on 12v so all you need to do is to tap into a 12v wire from the PSU to one of the Molex connectors and do the same for ground. If I remember correctly of the 4 wires that go to the molex connector, the red is 5v the 2 black are ground and the yellow is 12v. The easiest way probably is to get the vampire clamps from the ratshack or any auto parts store (ie. AutoZone, PepBoys). on the lilli side, if i remember correctly, the white striped wire is the 12v and the solid black is ground.

No need to cut up the lilliput cord, just buy a 12V automotive socket from Radio Shack for a couple bucks and wire your molex connector into that. Use a molex splitter or tap directly into one yellow wire and one black wire for the power.

thanks for the replies

I did do a search but couldnt find the answer I was after.

I am in the UK so don't have those shops here. If I cut the littliput wire, will I only have 2 wires a positive and earth ?

Is the white stripped one deffo positive ?

Will I still need to use the 'egg' regulator thing ?

cheers

the power off of your psu should be regulated...if it is..theres no use for the egg..if its not regulated..good luck with ur mobo...lol ....and use the egg

Yes, there will only be 2 wires. I'm not completely sure about the coloring but if you have a multimeter it will be easy to find out. I am almost sure that I found the color coding of the wires somewhere here in the forums, check the "all you need to know about the lilliput" thread.

as hanzacra posted... if you connect it to your PSU on a molex it should be regulated already so you don't need the egg, if you are hooking it up to any other 12v source I would keep the egg. What PSU are you using?

Dont forget a fuse as well, just saved my *** about 5 mins ago.

What fuse holder, and fuse type, do you use for this? Im actually running a Xenarc 700 TSV. I assume the fuse needs to be closer to one end of the cable, but not sure which one

justintime · 08-28-2005, 06:22 PM

ABout to wire the Xenarc... would like some pointers regarding the FUSE. What size fuse to use, and also what type fuse holder you suggest?

nsmoller · 08-28-2005, 06:27 PM

same model, i use 10 amp... you go buy a fuse holder at autozone or something, they have them, they go right inline... you should solder it inline!

Mad Ad · 08-28-2005, 06:47 PM

I made one of those for my lillipt, got the blank molex from maplin and the power adaptor with a pluggie from a boot sale ... see my reply in this thread here http://www.digital-car.co.uk/forum/viewtopic.php?t=1209

Thanks guys... I will buy a fuse holder from Autozone. Can you point me to a pic of a fuseholder that would be suitable for this? I have seen too many types of fuse holders, not really sure if any particular one is best for the job?

10 amp fuse?! Whoah, that sound like a lot!!!! Can't be right!

You know, I still cannot determine the right size of the barrel connector. RatShack has a few sizes, typically called A,B,C,D, etc. Anyone know for sure what size the Xenarc uses? I tried to visually compare, but could not find anything identical (only similar).
