Default ECM question?

For those of you who have replaced the computer on an L98 how difficult is the install? Is it fairly easy or should i dish out the $$$ for someone else to do it? Also how much should i expect to pay for the computer? Thanks for any info.

Its pretty easy.
Just remove the black hush panel, the 2 bolts on the ECM (it sits perpendicular to the floor) and gently tug on it til it comes down. Then just disconnect the wiring harness.

Dont forget to transfer the chip though.

Advance price: $87 for my 1986 last week, order only (next day) and you pay up front. Not bad!
