Problems with S14 swap help!

[Mixmastamunkh]

So I just bought a nice black 240sx 91. it was a 91 chassi with an s14 engine in it. unfortunatly the s14 swap led to problems with the wiring. my speedometer doesn't work along with several other dash lights. anyone else have this problem and if so what should i do? my wiring doesnt seem to match up with the swapped engine and i don't know what to do.
