Although most of the parts are concentrated around the bottom right area of the PCB, there are a few other parts hidden around the board that need to be added. R28 (Directly behind the analogue joystick port) tells the ASIC that the CPC has 128K instead of 64K. R55 (between the ASIC and first RAM IC) connects the NCAS1 signal to the new RAM. LR04 and C39 (above the 26way floppy header) are required to supply the floppy disk with power. C39 is the only passive component with poles. Make sure that it is soldered in the correct position, with the minus pole towards the rear of the CPC.
Amstrad action published some handy maps showing where the relevant components are located. [[Amstrad_Action,_Issue_90,_Mar_1993|Issue ninety]] covers the RAM components, and [[Amstrad_Action,_Issue_91,_Apr_1993|issue ninety-one]] covers the disc components - high(er) quality scans of these sections are shown below (note that the wire link and C99 mentioned in the RAM map doesn't seem to be required) :
