Suzuki alto + sj410 jeep 1000cc Timing & Distributor or Firing Order Method

For one reason or another I need to sort the timing on my sj410, the only timing marks I have are on the cam shaft in the form of an arrow on the timing pulley that says '88', and on the top of the timing belt cover in the 12 o'clock position. There are no timing marks on the crankshaft pulley anywhere, so my question to you is, when piston 1 is at TDC on the compression stroke, where should the cam shaft timing mark be in relation to the mark above it on the casing? Hopefully she will be ready for taking out this weekend if I get this sorted
