The PIC is not blank its already soldered onto a piece of working equipment.
The new devices we reprogram with a laptop that has special software that sends data via the serial port straight into the max232e thats wired directly to the PIC. The older devices are exactly the same except no connection port and no mac232e chip. from what i can see there are only 3 connections from the max232 the the PIC
I just don't know what they connect to..... RB5,RB6,RB7,Vdd,Vss or MCLR ?

Use Google and do a little research about ICSP, that might help.

I hope you don't get the idea that i came here without trying to research this stuff.

If someone could tell me what pins on the PIC the 3 data lines connect to??? Is that asking 2 much?

The problem here is without knowing the hardware or software differences between the two versions, who's to say the second version (with the max232) was loaded with a bootloader to allow for field updates? The first version could have been programed using ICSP or could have just been programmed and soldered into the circuit without regard for future updates.... hence the second version that is field updateable.The new devices we reprogram with a laptop that has special software that sends data via the serial port straight into the max232e thats wired directly to the PIC.

Wisdom is knowing what path to take next... Integrity is taking it.

OK good point. Thanks for the reply. that is a very real possibility. Since the PIC chips are exactly the same I think it may be worth a try to save some money.
