The way I would/have do/done this is to solder in a socket. That way the EPROM will not be damaged and you can take the map/chip with you if you change cars.
More importantly, as well as just cutting the link to de-select the original map, the fitting of a remote (dash mounted ?) switch, replacing the link, means you can switch between maps on the fly.
Anyway, I was offering to help out, but I'm afraid you've missed the boat as I'm not going to have the time in the next few weeks as .I have my own car to get ready. Not enough hours in the day from now on in........
