sbc v8 swap speedo and park light issues

I have recently completed my sbc swap in my 1993 yj. Ok well not completed but close, I have a few issues first off does anyone know how to get the speedo working,Ii used the stock tranfer case with a 700r4 trans? Also I can not seem to get the parking lights and dash lights to work, all other lights work including hazzards which is just the parking lights flashing. I built this for my 16 year old daughter and need to get these issues fixed she has been waiting a long time and want to make this safe.

thanks

Speedo- Have you pulled the speedo gear from the inside of the transfer to see if its stripped? If thats good the grab the inside end of the speedo cable and turn it to see if it turns the speedo in the dash. If not then replace the cable.

Lights- Have you checked all your fuses and relays? What about the grounds, are they clean and tight? Make sure you check your bulbs too

Cable should be electronic on a 93 IIRC. You need the Jeep sender to run the Jeep speedo.

True, I totally forgot about that. Thank you for the correction.

Hmmm, never tried it!
AFAIK the ecm sends the power signal to the sensor, then the sensor returns that signal to the speedo in a pulse.
If you are wanting no ecm, then either go to a mechanical speedo, or go aftermarket.

Seeing as the speedo is driven off the transfer case, tranny is irrelevant pretty much.
Up to and including 1991, YJ's were mechanical speedo IIRC.
Price up both ways and go from there.
