    Dirt Cheap DIY ALDL Cable for TBI

    Sorry if this has already been done but I originally used this thread to make an aldl cable that worked but was clumsy and needed a separate cable to connect to my PC: http://www.gearhead-efi.com/Fuel-Inj...USB-ALDL-Cable. Well that thread was too long so I decided a new write up with all the info in the first page would be better. I also lost my original ALDL chip and had to figure out a different one, so here it is:

    Found the FT232RL cable on ebay for $3.00 and only had to wait 9 days to get it from China

    Took the plastic cable end off:

    Popped open the USB end

    Clipped out all wires except the ground, RXD, and TXD

    Put the USB end back together with a few small dabs of superglue and then soldered the RXD & TXD wires together and the ground/blue wires and left a few wires to make the end stronger.

    Squished the connectors down a bit to fit into the ALDL port and added heat shrink and it works great

    Nice work.

    The previous threads lost pictures and links to ebay parts were stale.
